Guide for Authors
The International Journal on the Science and Technology of Electrochemical Energy Systems
Aims & scope
The Journal of Power Sources provides an interdisciplinary forum on all aspects of the science,
technology and commercialization of primary/secondary batteries and fuel cells, supercapcitors, photo-electrochemical cells, including
their applications in:
• Portable electronics
• Hybrid Electric Vehicles
• UPS powering systems
•
Remote wind- and/or solar-based powering systems
• Satellites and deep space probes.
The principal objective of the scientific
literature is that it should be the secure repository of the growing body of scientific knowledge. The 'literature' should provide a
clear view of the current status of any branch of knowledge and can thus be used by active workers as a vital tool in the design of ongoing
studies. In order to be of maximum usefulness it is important that published literature should be readily comprehensible to non-specialists
in the subject field.
This purpose can be achieved only if the following three broad criteria are adopted for material contributed
to the publication process:
1. A manuscript must describe new science. It should add to the "tree of knowledge'". Duplication
serves only to clutter the published literature and in some cases can lead to copyright problems.
2. The subject material must be
sound science, containing no errors of fact or logic.
3. Papers must be written in the clearest, most precise, language possible.
All terms need to be clearly defined and specialist jargon must be avoided.
Types
of paper
The Journal of Power Sources accepts research papers, short communications, and reviews.
Short communications
report the results of preliminary studies, partial research results from an ongoing study, results from studies limited in scope, or
raise a critical issue or question based on such results. Short Communications should follow all the basic requirements of full paper
manuscripts, but must not exceed 12 double-spaced manuscript pages including figures, tables, text and references.
An abstract must
be submitted with a Short Communication.
Please note: All papers that are 6 or less typeset pages in length will be automatically
made Short Communication.
Please select the appropriate article type from the drop down menu in the online submission system. When
submitting papers for conference issues, please also clearly indicate on
both the title page and in the covering letter at which
conference the submitted work was presented.
Ethics in Publishing
For information on Ethics in Publishing and Ethical guidelines for journal publication

http://www.elsevier.com/ethicalguidelines.
Conflict of interest
All authors are requested to disclose any actual or potential conflict of interest
including any financial, personal or other relationships with other people or organizations within three years of beginning the submitted
work that could inappropriately influence, or be perceived to influence, their work. See also
http://www.elsevier.com/conflictsofinterest.
Submission declaration
Submission of an article implies that the work described has not been published previously
(except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication
elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was
carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, without
the written consent of the copyright-holder.
Authors of papers containing
any amount of previously rejected material must identify the manuscript number of the previously rejected manuscript in the covering
letter as well as in the author notes, and summarize the reasons for re-submission.
Contributors
Each author is required to declare his or her individual contribution to the article: all authors must have materially participated
in the research and/or article preparation, so roles for all authors should be described. The statement that all authors have approved
the final article should be true and included in the disclosure.
Copyright
Upon
acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' (for more information on this and copyright
see
http://www.elsevier.com/copyright). Acceptance of the agreement will ensure the widest possible dissemination of information.
An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement'
form or a link to the online version of this agreement.
Subscribers may reproduce tables of contents or prepare lists of articles
including abstracts for internal circulation within their institutions. Permission of the Publisher is required for resale or distribution
outside the institution and for all other derivative works, including compilations and translations (please consult
http://www.elsevier.com/permissions).
If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit
the source(s) in the article. Elsevier has preprinted forms for use by authors in these cases: please consult
http://www.elsevier.com/permissions.
Retained author rights
As an author you (or your employer or institution) retain certain rights; for details
you are referred to:
http://www.elsevier.com/authorsrights.
Role of the
funding source
You are requested to identify who provided financial support for the conduct of the research and/or preparation
of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation
of data; in the writing of the report; and in the decision to submit the paper for publication. If the funding source(s) had no such
involvement then this should be stated. Please see
http://www.elsevier.com/funding.
Funding body agreements and policies
Elsevier has established agreements and developed policies to allow authors whose
articles appear in journals published by Elsevier, to comply with potential manuscript archiving requirements as specified as conditions
of their grant awards. To learn more about existing agreements and policies please visit
http://www.elsevier.com/fundingbodies.
Language and language services
Please write your text in good English (American or British usage is accepted,
but not a mixture of these). Authors who require information about language editing and copyediting services pre- and post-submission
please visit
http://www.elsevier.com/languagepolishing or our customer support site at
http://epsupport.elsevier.com
for more information. Please note Elsevier neither endorses nor takes responsibility for any products, goods or services offered by outside
vendors through our services or in any advertising. For more information please refer to our Terms & Conditions:
http://www.elsevier.com/termsandconditions.
Submission
Submission to this journal proceeds totally online and you will be guided stepwise through
the creation and uploading of your files. The system automatically converts source files to a single PDF file of the article, which is
used in the peer-review process. Please note that even though manuscript source files are converted to PDF files at submission for the
review process, these source files are needed for further processing after acceptance. All correspondence, including notification of
the Editor's decision and requests for revision, takes place by e-mail removing the need for a paper trail.
Referees
The Editor first evaluates all manuscripts. Those rejected at this stage are insufficiently original,
have serious scientific flaws, have poor grammar or English language, or are outside the aims and scope of the journal. Those that meet
the minimum criteria are passed on to 2 experts for review. Referees advise the editor, who is responsible for the final decision to
accept or reject the article.
Please note: Editor's Decision is final.
Revision
time
Should authors be requested by the editor to revise the text, the revised version should be submitted within one month.
After this period, the article will be regarded as a new submission.
Use of wordprocessing software
It is important that the file be saved
in the native format of the wordprocessor used. The text should be in single-column format. Keep the layout of the text as simple as
possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the wordprocessor's
options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. Do not embed "graphically
designed" equations or tables, but prepare these using the wordprocessor's facility. When preparing tables, if you are using a table
grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns.
The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with
Elsevier:
http://www.elsevier.com/guidepublication). Do not import the figures into the text file but, instead, indicate
their approximate locations directly in the electronic text and on the manuscript. See also the section on Electronic illustrations.
To avoid unnecessary errors you are strongly advised to use the "spell-check" and "grammar-check" functions of your wordprocessor.
Article structure
Subdivision - numbered sections
Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2,
etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to
"the text". Any subsection may be given a brief heading. Each heading should appear on its own separate line.
Material and methods
Provide sufficient detail to allow the work to be reproduced. Methods already
published should be indicated by a reference: only relevant modifications should be described.
Theory/calculation
A Theory section should extend, not repeat, the background to the article already dealt with in
the Introduction and lay the foundation for further work. In contrast, a Calculation section represents a practical development from
a theoretical basis.
Results
Results should be clear and concise.
Discussion
This should explore the significance of the results of the work, not repeat them. A combined
Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.
Conclusions
The main conclusions of the study may be presented in a short Conclusions section, which
may stand alone or form a subsection of a Discussion or Results and Discussion section.
Glossary
Please supply, as a separate list, the definitions of field-specific terms used in your article.
Appendices
If there is more than one appendix, they should be identified as A, B, etc. Formulae and
equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on.
Vitae
Include in the manuscript a short (maximum 100 words) biography of each author, along with a
passport-type photograph accompanying the other figures.
Essential title page information
•
Title.
Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations
and formulae where possible.
•
Author names and affiliations.
Where the family name may be ambiguous (e.g., a
double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names.
Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address.
Provide the full postal address of each affiliation, including the country name, and, if available, the e-mail address of each author.
•
Corresponding author.
Clearly indicate who will handle correspondence at all stages of refereeing and publication, also
post-publication.
Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address
and the complete postal address.
•
Present/permanent address.
If an author has moved since the work described
in the article was done, or was visiting at the time, a "Present address" (or "Permanent address") may be indicated as a footnote to
that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript
Arabic numerals are used for such footnotes.
Abstract
A concise and factual
abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An
abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided,
but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential
they must be defined at their first mention in the abstract itself.

of Power Sources List of Acceptable Acronyms and Abbreviations, click
here
to view.
Keywords
Immediately after the abstract, provide a maximum of
6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, "and", "of"). Be
sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing
purposes.
Abbreviations
Define abbreviations that are not standard in
this field in a footnote to be placed on the first page of the article. Such abbreviations that are unavoidable in the abstract must
be defined at their first mention there, as well as in the footnote. Ensure consistency of abbreviations throughout the article.
Acknowledgements
Collate acknowledgements in a separate section at the end of the article before the references
and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided
help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).
Nomenclature
Follow internationally accepted rules and conventions: use the international system of units
(SI). If other quantities are mentioned, give their equivalent in SI. You are urged to consult IUPAC:
http://www.iupac.org/
for further information.
Units should be given in the correct format for this journal:
mVs
-1 not mV/s mAhg
-1
not mAh/g
Math formulae
Present simple formulae in the line of normal
text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables
are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have
to be displayed separately from the text (if referred to explicitly in the text).
Footnotes
Footnotes should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many
wordprocessors build footnotes into the text, and this feature may be used. Should this not be the case, indicate the position of footnotes
in the text and present the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.
Table footnotes
Indicate each footnote in a table with a superscript lowercase letter.
Artwork
Electronic artwork
General points
• Make sure you use uniform lettering and sizing of your original artwork.
• Save text in illustrations as "graphics"
or enclose the font.
• Only use the following fonts in your illustrations: Arial, Courier, Times, Symbol.
• Number
the illustrations according to their sequence in the text.
• Use a logical naming convention for your artwork files.
•
Provide captions to illustrations separately.
• Produce images near to the desired size of the printed version.
• Submit
each figure as a separate file.
A detailed guide on electronic artwork is available on our website:
http://www.elsevier.com/artworkinstructions
You are urged to visit this site; some excerpts from the detailed information are given here.
Formats
Regardless
of the application used, when your electronic artwork is finalised, please "save as" or convert the images to one of the following formats
(note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):
EPS: Vector drawings.
Embed the font or save the text as "graphics".
TIFF: color or grayscale photographs (halftones): always use a minimum of 300 dpi.
TIFF: Bitmapped line drawings: use a minimum of 1000 dpi.
TIFF: Combinations bitmapped line/half-tone (color or grayscale): a
minimum of 500 dpi is required.
DOC, XLS or PPT: If your electronic artwork is created in any of these Microsoft Office applications
please supply "as is".
Please do not:
• Supply embedded graphics in your wordprocessor (spreadsheet, presentation)
document;
• Supply files that are optimised for screen use (like GIF, BMP, PICT, WPG); the resolution is too low;
•
Supply files that are too low in resolution;
• Submit graphics that are disproportionately large for the content.
Color artwork
Please make sure that artwork files are in an acceptable format (TIFF, EPS or MS Office
files) and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure,
at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether
or not these illustrations are reproduced in color in the printed version.
For color reproduction in print, you will receive information
regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for color in print or on
the Web only. For further information on the preparation of electronic artwork, please see
http://www.elsevier.com/artworkinstructions.
Please note: Because of technical complications which can arise by converting color figures to "gray scale" (for the printed version
should you not opt for color in print) please submit in addition usable black and white versions of all the color illustrations.
Figure captions
Ensure that each illustration has a caption. Supply captions separately, not attached
to the figure. A caption should comprise a brief title (
not on the figure itself) and a description of the illustration. Keep
text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.
With axes captions, the first letter of the first word only should be in capital type (except for acronyms);
units should be in the correct format (see below) and should follow a stroke, /. An example is as follows:
Tables
Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables
below the table body and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and
ensure that the data presented in tables do not duplicate results described elsewhere in the article.
Each table should have a concise title that makes the general meaning understandable with reference to the
text. Authors should check that every table is cited in the text.
An example of Table layout is as follows:
Table 4
a Results in brackets denote the number of inserted lithium ions per vanadium oxide formula unit (assumed to be V2O5).
References
Citation in text
Please ensure that
every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be
given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the
text. If these references are included in the reference list they should follow the standard reference style of the journal and should
include a substitution of the publication date with either "Unpublished results" or "Personal communication" Citation of a reference
as "in press" implies that the item has been accepted for publication.
Web references
As a minimum, the full URL should be given. Any further information, if known (DOI, author names, dates, reference to a source publication,
etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired,
or can be included in the reference list.
Reference style
Text:
Indicate references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s)
must always be given.
Example: "..... as demonstrated [3,6]. Barnaby and Jones [8] obtained a different result ...."
List:
Number the references (numbers in square brackets) in the list in the order in which they appear in the text.
Examples:
Reference to a journal publication:

Journal of Power Sources.
Use of the Digital Object Identifier
The
Digital Object Identifier (DOI) may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character
string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore,
it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic
information. The correct format for citing a DOI is shown as follows (example taken from a document in the journal
Physics Letters
B):
doi:10.1016/j.physletb.2003.10.071
When you use the DOI to create URL hyperlinks to documents on the web, they are guaranteed
never to change.
Proofs
One set of page proofs (as PDF files) will be
sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent by post) or, a link will
be provided in the e-mail so that authors can download the files themselves. Elsevier now provides authors with PDF proofs which can
be annotated; for this you will need to download Adobe Reader version 7 (or higher) available free from
http://www.adobe.com/products/acrobat/readstep2.html.
Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the
Adobe site:
http://www.adobe.com/products/acrobat/acrrsystemreqs.html#70win.
If you do not wish to use the PDF annotations
function, you may list the corrections (including replies to the Query Form) and return them to Elsevier in an e-mail. Please list your
corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including
replies to the Query Form) on a printout of your proof and return by fax, or scan the pages and e-mail, or by post. Please use this proof
only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the
article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible
to get your article published quickly and accurately. Therefore, it is important to ensure that all of your corrections are sent back
to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed.
Proofreading is solely your responsibility. Note that Elsevier may proceed with the publication of your article if no response is received.
Offprints
The corresponding author, at no cost, will be provided with a PDF file of the article via e-mail.
The PDF file is a watermarked version of the published article and includes a cover sheet with the journal cover image and a disclaimer
outlining the terms and conditions of use. Additional paper offprints can be ordered by the authors. An order form with prices will be
sent to the corresponding author.
For inquiries relating
to the submission of articles (including electronic submission where available) please visit this journal's homepage. You can track accepted
articles at
http://www.elsevier.com/trackarticle and set up e-mail alerts to inform you of when an article's status has
changed. Also accessible from here is information on copyright, frequently asked questions and more. Contact details for questions arising
after acceptance of an article, especially those relating to proofs, will be provided by the publisher.
