Journal of Power Sources Formatting Requirements: The Submission Package Guide

Journal of Power Sources is not mainly testing whether authors can follow Elsevier house style. It is testing whether the package behaves like a serious electrochemical paper whose evidence architecture matches its claim.

Our analysis of electrochemical packages is that formatting discipline matters most when the result is interesting but the package still looks under-normalized. A clean JPS package reads like a paper built for specialist scrutiny. A messy one reads like a materials paper trying to pass as a power-sources paper.

The journal's current guide explicitly lists Research Papers, Reviews, and Perspectives with distinct word and figure budgets. That means article type is not a cosmetic dropdown choice. It determines whether the whole package feels correctly judged.

We have found that many weak submissions start with the wrong package choice. A Research Paper with unresolved evidence sprawl or a Perspective trying to carry too much technical validation both signal that the manuscript has not been edited tightly enough for JPS.

JPS currently limits Research Papers and Reviews to 8 figures in the main manuscript and Perspectives to 5, with additional figures allowed as supplementary material. That figure budget matters because electrochemical papers often accumulate panels faster than their main argument improves.

Editors specifically screen for whether the figure count is being used to tell one rigorous story or to compensate for unresolved editorial choices. If the package needs more than 8 main figures because the paper still has three partially competing centers, the format is telling on the science.

The current guide for authors tells researchers to read the relevant good-practice guide for batteries, supercapacitors and related hybrid capacitors, or fuel cells and electrolysis cells before submitting. That is a major signal about how JPS thinks about package quality.

In practical terms, this means the manuscript should already make it easy to verify:

• what electrochemical system is being studied
• which testing norms or benchmarks were followed
• whether the conclusions match the actual protocol
• how degradation, diagnostics, or validation support the main claim
• whether the package reflects device-level seriousness rather than lab-only optimization

We have found that many manuscripts miss the journal not because the science is uninteresting, but because the formatting and evidence layers still look lighter than the journal's own good-practice posture.

The current JPS guide asks for a concise abstract up to 200 words, 1 to 7 keywords, encouraged highlights, and an encouraged graphical abstract. That combination makes the first screen unusually important.

The best JPS front-end packages are not flashy. They are disciplined. The abstract, keywords, highlights, and main figures all describe the same electrochemical claim at the same level of seriousness.

JPS currently requires authors to state the availability of data at submission, and it says the statement will appear with the published article on ScienceDirect. The guide also points authors toward data deposit, citation, and linking requirements.

That means the package should already have:

• a stable data-availability statement
• repository or non-sharing logic that can survive publication
• supplementary files cited cleanly in the manuscript
• editable source files for text, tables, and figures
• separate artwork files with logical names

We have found that weak data statements often reveal a broader package problem. If the authors do not yet know how the data layer will be presented, the manuscript often still has unresolved questions about evidence ownership too.

In our pre-submission review work with Journal of Power Sources packages, we have found that formatting failures are usually evidence-architecture failures rather than style failures.

The article type is overclaiming or underclaiming the real package. We have found that many weak submissions choose a container that does not match the true size of the story.

The figure set is too big for the argument it is making. Editors specifically screen for whether the main manuscript tells one credible electrochemical story.

The good-practice layer is missing from the package. Our analysis of weaker papers is that reporting and testing often look less normalized than the journal expects.

The data statement is generic. That creates immediate friction in a journal that explicitly asks for data availability at submission.

The supplement is doing repair work. If the package needs supplementary files to become believable rather than merely richer, the main format is not ready yet.

Use a Journal of Power Sources formatting and readiness review if you want one pass across article type, figure budget, data statement, and validation architecture before submission.

Read the article type, abstract, highlight bullets, first two figure titles, and data-availability statement in one sitting. Those pieces should sound like one coherent Journal of Power Sources paper. If one part sounds like a device paper, another sounds like a materials paper, and another still sounds provisional, the package is not ready yet.

This is also the moment to catch avoidable Elsevier friction: figure overages, missing separate artwork files, and a generic data statement that will not survive final publication.
