How to use this page well
These pages work best when they behave like tools, not essays. Use the quick structure first, then apply it to the exact journal and manuscript situation.
Question | What to do |
|---|---|
Use this page for | Getting the structure, tone, and decision logic right before you send anything out. |
Most important move | Make the reviewer-facing or editor-facing ask obvious early rather than burying it in prose. |
Common mistake | Turning a practical page into a long explanation instead of a working template or checklist. |
Next step | Use the page as a tool, then adjust it to the exact manuscript and journal situation. |
Quick answer: a strong Journal of Power Sources cover letter proves that your electrochemical data is rigorous, properly reported, and relevant to a real energy storage or conversion problem. With an IF of 7.8 (JCR 2024) and a 30-35% acceptance rate, this Elsevier flagship screens hard at triage, the editor's first question is whether the device-level data is serious, not whether the material concept sounds novel.
What Journal of Power Sources Editors Screen For
Criterion | What They Want | Common Mistake |
|---|---|---|
Electrochemical rigor | Sufficient cycling data, proper normalization, multiple C-rates, realistic conditions | Reporting half-cell data only without full-cell results or justification |
Device relevance | Connection to a real energy storage or conversion problem (batteries, fuel cells, supercapacitors) | Submitting a materials synthesis paper with minimal device-level testing |
Practical significance | Beyond incremental improvement - mechanism insight or practical application advance | Claiming a novel material without meaningful performance context |
Honest benchmarking | Data reported with reproducibility and proper comparison to prior work | Selective benchmarking or missing state-of-the-art comparisons |
Complete testing | Full electrochemical characterization appropriate for the device type | Too few cycles, single C-rate, or incomplete characterization |
What the official sources do and do not tell you
The official Journal of Power Sources author guidelines describe the Elsevier Editorial Manager workflow and the journal's broad energy scope, but they do not spell out how aggressively editors now filter for complete electrochemical testing and honest data reporting.
What the editorial model does imply is clear:
- the journal is device-oriented: batteries, fuel cells, supercapacitors, solar cells, material synthesis alone is not enough
- editors expect sufficient cycling data, proper normalization, multiple C-rates, and realistic testing conditions
- incomplete electrochemical testing (too few cycles, half-cell only, single C-rate) is the primary trigger for desk rejection
That means leading with device-level electrochemical results matters more than claiming a novel material.
What the editor is really screening for
At triage, the editor is usually asking:
- is the electrochemical testing rigorous enough to be meaningful (sufficient cycles, proper normalization, multiple conditions)?
- does the work connect to a real energy storage or conversion problem, or is it a materials paper with minimal device relevance?
- does the paper go beyond incremental improvement to reveal something about mechanism or practical application?
- is the data reported honestly, with reproducibility and proper benchmarking against prior work?
A cover letter that answers the first question in the opening paragraph will survive triage.
A practical template you can adapt
Dear Editor,
We submit the manuscript "[TITLE]" for consideration as a
research article in Journal of Power Sources.
This study addresses [specific energy storage or conversion
problem, naming device type and performance limitation]. We
show that [main finding with quantitative electrochemical
result and testing conditions, e.g., capacity, retention,
cycles, C-rate].
Compared to [relevant benchmark], our approach achieves
[specific improvement with numbers]. This result matters for
practical devices because [explain relevance to real-world
performance, manufacturability, or scalability].
The work fits Journal of Power Sources because it bridges
[materials or electrochemical insight] with [device-level
performance data].
The work is original, not under consideration elsewhere, and
approved by all authors.
Sincerely,
[Name]The sentence stating quantitative electrochemical results under realistic testing conditions is the single most important element.
Mistakes that make these letters weak
- reporting only half-cell data without full-cell results or a clear justification for the omission
- claiming "excellent electrochemical performance" or "outstanding cycling stability" without specific numbers or testing conditions
- submitting a materials synthesis paper that stops at XRD and SEM without any device-level electrochemical testing
- ignoring scalability and cost considerations for a journal with a strong practical orientation
- leading with the synthesis route instead of the electrochemical results, editors want performance first, then how you achieved it
What should drive the submission decision instead
Before polishing the letter further, confirm the journal fit. Journal of Power Sources is a device-oriented energy journal, not a fundamental electrochemistry outlet. If the paper is about electrode reaction mechanisms without a connection to device performance, it likely belongs at Electrochimica Acta or Journal of the Electrochemical Society instead. Check the journal's own author guidelines to verify alignment.
Practical verdict
The strongest Journal of Power Sources cover letters lead with quantitative device data, name the energy problem being solved, and prove the testing is rigorous and honest. They show the editor that the electrochemical characterization is complete enough to survive peer review.
So the useful takeaway is this: open with the device-level result and testing conditions, connect the finding to a practical energy problem, and be honest about what the data shows. A Journal of Power Sources cover letter framing check is the fastest way to pressure-test whether your framing already does that before submission.
What Journal of Power Sources Editors Look For
Journal of Power Sources (Elsevier, IF 7.8, JCR 2024) covers batteries, fuel cells, supercapacitors, and energy storage. It ranks Q1 at 7th of 44 journals in Electrochemistry with a JCI of 1.24. Cover letter requirements:
Element | What to include | Why it matters |
|---|---|---|
Device/system performance | Specific numbers (capacity, cycling stability, efficiency) | JPS editors scan for quantitative advances, not qualitative claims |
Comparison to state-of-art | How your results compare to the best published data | "Improved performance" without benchmarks gets ignored |
Practical relevance | Scalability, cost, or commercial applicability | JPS values applied energy storage over fundamental materials science |
Novelty beyond materials | What's new about the approach, not just the material | New composition alone isn't enough if the mechanism is the same |
JPS accepts approximately 30% of submissions. For battery and fuel cell researchers, it's a reliable Q1 venue that values thorough characterization over flashy results. A Journal of Power Sources cover letter framing check can assess whether your paper's framing meets the journal's editorial threshold.

Frequently asked questions
It should state the energy storage or conversion problem your work addresses and include quantitative electrochemical results with testing conditions. The editor screens for device-level data and practical relevance, not just material novelty.
Reporting half-cell data only without full-cell results or justification. For a device-oriented journal, half-cell characterization alone often signals incomplete testing, which triggers desk rejection.
Journal of Power Sources has a JCR 2024 impact factor of 7.8 and a 5-year IF of 8.4, ranking Q1 at 7th of 44 in Electrochemistry. The acceptance rate is roughly 30 to 35 percent, with a desk rejection rate around 30 to 40 percent.
Journal of Power Sources is centered on energy storage and conversion devices such as batteries, fuel cells, and supercapacitors. Electrochimica Acta covers electrochemistry more broadly including corrosion, electrodeposition, and fundamental kinetics. If the paper is about a working device, Journal of Power Sources is the better fit.
