ACS Applied Energy Materials Submission Guide: Portal, Cover-Letter Application Test & Routing

This is the single most-skipped piece of ACS Applied Energy Materials submission advice:

ACS AAEM requires authors to name the application explicitly in the cover letter. From the ACS-required wording: the cover letter must include a paragraph explaining "what application is described in the work" alongside five reviewer names.

We read this cover-letter sentence as a routing signal across the ACS energy and materials portfolio:

Cover letters that cannot name a specific application get routed elsewhere or rejected for scope drift at the editor triage.

ACS Applied Energy Materials publishes six article types with type-specific caps.

TOC graphic required (ACS-specific dimensions). Manuscript format U.S. Letter. If a crystal structure is an essential part of the manuscript, the CIF and checkCIF report must accompany the submission, and the guidelines say CIFs, structure factor tables and checkCIF reports should be submitted to the CCDC prior to manuscript submission. The guidelines give no figure limit for Articles.

ACS publishes median days for ACS Applied Energy Materials (2025 data, current as of 6/17/2026): 6.7 days from submission to a first editorial decision without peer review, 28.9 days to a first decision with peer review, 67.9 days to acceptance (including revision time), and 7.8 days from acceptance to ASAP publication. The stages below follow the author guidelines:

• Day 0, ACS Publishing Center upload: Submission lands in the portal. ACS Publications may screen manuscripts for similarity to published material with iThenticate. If a crystal structure is essential to the manuscript, the CIF and checkCIF report go with the submission, and the guidelines say failure to provide the CIF will delay review.
• Editorial triage: The handling editor reads the cover letter, which must explain why the manuscript is appropriate for the journal and clearly indicate what application is described, and decides whether to send the manuscript out for review. The guidelines say the final decision on suitability rests solely with the Editor.
• Peer review: All manuscripts are subject to critical, anonymous peer review.
• Revision and publication: A manuscript sent back for revision should be returned as soon as possible, and a revision not received within 21 days is considered withdrawn. On resubmission a clean final file and a marked copy are required. After acceptance, ACS reports a median of 7.8 days to ASAP publication.

The single most consequential decision before submission is which ACS energy or applied-materials venue to target. The cover-letter application test is the routing oracle.

The ACS Applied family includes ACS AMI (broad), ACS Applied Nano Materials, ACS Applied Energy Materials (this), ACS Applied Bio Materials, ACS Applied Polymer Materials, ACS Applied Electronic Materials, ACS Applied Optical Materials, and ACS Applied Engineering Materials; ACS's metrics table also lists ACS Applied Catalysis, launched in 2026. If the editors decline a submission they may suggest a transfer to another ACS journal.

AAEM editors screen on three operational signals at the editorial triage:

1. Cover-letter application named explicitly. Per ACS-required wording, the cover letter must name what application is described in the work. Cover letters that argue scientific novelty without naming a specific application return at the editor triage.

1. Materials novelty for applied energy. ACS's journal page says AAEM particularly encourages work that demonstrates mechanistic insight, materials innovation, and clear relevance to sustainable energy technologies; in our reading, that means a materials contribution (new compound, new structure, new property regime, new mechanism). Pure-applied work using existing materials routes to Journal of Power Sources or Applied Energy.

1. Format-specific caps respected. Article: no more than 300-word abstract, typically no more than 70 references. Letter: less than 100-word abstract, no more than 30 references. Length mismatches (Letter-shape claim at Articles length, or vice versa) route to ACS Energy Letters or fail the editor triage.

Recent issues span battery materials (Li-ion, Na-ion, solid-state, beyond-Li, K-ion), photovoltaic materials (silicon, perovskite, organic, tandem), fuel cell materials (PEMFC, SOFC, alkaline), electrocatalysis materials (HER, OER, ORR, CO2 reduction, nitrogen reduction), photocatalysis for solar fuels and water splitting, hydrogen production and storage materials, supercapacitor materials, thermoelectrics, and emerging energy materials including machine-learning-discovered systems.

Across energy-materials manuscripts targeting ACS Applied Energy Materials, three recurring decision risks matter most across submissions that AAEM editors filter out at the desk-screen stage. (Per ACS published author guidelines, AAEM requires a cover letter explaining why the manuscript is appropriate for AAEM AND clearly indicating what application is described (we read this sentence as a routing signal across the ACS energy-and-materials portfolio);

Article abstracts are limited to 300 words with references typically limited to 70, and Letters need an abstract under 100 words with no more than 30 references; crystal-structure data goes to the CCDC before submission, with the CIF and checkCIF report submitted with the manuscript; a graphical summary for the table of contents is required; submissions go through the ACS Publishing Center, where manuscripts may be screened for similarity to published material;

ACS reports a median of 28.9 days from submission to a first decision with peer review (2025 data).

Manuscripts essentially reporting data or applications of data are explicitly not suitable per the published guidelines.) Use the three checks below before you open ACS Publishing Center AAEM upload slot.

Application-framing failure: pure-fundamentals materials chemistry without applied-energy framing

Across AAEM-targeted manuscripts, we consistently see authors submit work where the underlying contribution is fundamental materials chemistry (new precursor route, new ligand design, new self-assembly principle, new crystal structure characterization, new electronic-structure DFT calculation, new spectroscopic characterization) or pure property characterization (new optical / magnetic / electronic / structural property measurement) without articulating an applied-energy contribution that the AAEM scope requires.

AAEM editors apply the documented cover-letter application test at desk:

• the cover letter must name a specific energy application (lithium-ion battery cathode with named chemistry: LFP / NMC / NCA / LMR / LMNO / sulfur / silicon-anode

• supercapacitor with named electrolyte and electrode chemistry

• fuel cell electrode with named PGM / non-PGM catalyst chemistry

• solar cell with named absorber: perovskite / kesterite / DSSC / OPV / quantum-dot

• thermoelectric with named ZT regime and operating temperature

• electrocatalysis with named reaction: HER / OER / ORR / CO2RR / NRR / N2RR

• photocatalysis with named reaction and quantum-efficiency target

• electrochromic / thermochromic with named switching range

• redox-flow battery with named electrolyte couple

• biofuel cell with named substrate)

• the abstract must lead with the applied-energy advance (not the materials-chemistry novelty)

• the manuscript must demonstrate the materials advance in the applied-energy context with realistic device-relevant operating conditions

Manuscripts that read as fundamental materials chemistry with energy as decoration get redirected at the editorial stage to: Chemistry of Materials (fundamental materials chemistry), JACS (broad chemistry significance), ACS Energy Letters (urgent broad-energy with letter format), Inorganic Chemistry (inorganic synthesis), Crystal Growth & Design (crystal-engineering focus), or Nature Energy / Joule (high-IF energy materials with comprehensive application validation).

The fix is to either reframe with explicit applied-energy framing (specific named application, performance metrics in realistic conditions, device-relevant operating regime) or route honestly to the fundamental-chemistry sibling venue.

Materials-novelty failure: applied energy-systems work without a materials advance

We frequently see AAEM manuscripts submit work where the contribution is pure-applied (device performance optimization on established materials, scale-up of established synthesis, systems-integration study, electrode-architecture engineering with established active material, separator engineering, current-collector engineering, electrolyte additive optimization, cell-format study, module-level engineering, manufacturing process optimization) without articulating the materials novelty AAEM requires.

AAEM handling editors specifically check whether the contribution includes a materials advance: a new compound or composition (with named structural formula and characterization), a new crystal structure (with CIF + CheckCIF + CCDC deposition), a new electrode-material design at the molecular / nanoscale level (not just a new electrode geometry), a new electrolyte chemistry (not just a new electrolyte concentration), a new interface chemistry (not just a new coating thickness), a new property regime achieved through chemistry (not just optimization within existing regime).

Manuscripts where the materials are established and the contribution is application engineering get redirected at the editorial stage to:

Journal of Power Sources (Elsevier, electrochemical-power-source application focus), Applied Energy (Elsevier, applied-energy systems including renewables / storage / efficiency), Energy & Environmental Science (RSC, broader energy-and-environment scope), Energy Storage Materials (Elsevier, broad energy-storage including device work), Journal of Energy Storage (Elsevier, applied energy-storage), Energy Conversion and Management (Elsevier, energy-systems integration), Renewable Energy (Elsevier, broad renewable), Solar Energy (Elsevier, solar-systems engineering), Journal of Renewable and Sustainable Energy (AIP, broad scope including engineering), or IEEE Transactions on Sustainable Energy / TPEL / TIE for power-electronics-focused energy work.

The fix is to either add genuine materials novelty (new chemistry, new structure, new interface design at the molecular level) before submission or route to the pure-applied sibling venue.

Format-routing failure: Article and Letter scope drift between AAEM and ACS Energy Letters

The third recurring pattern in AAEM-targeted manuscripts is format / scope misalignment between AAEM (the materials-novelty applied-energy venue accepting Articles at no more than 300-word abstract and typically no more than 70 references, plus shorter Letters at less than 100-word abstract and no more than 30 references) and ACS Energy Letters (the broader-energy letter-format venue accepting only Letters for time-sensitive urgent broad-energy work without strict materials-novelty requirement, with stricter length limits and faster turnaround).

AAEM editors specifically check at desk: whether a submitted Article has materials novelty justifying the longer comprehensive Article format (not a Letter padded to Article length); whether a submitted Letter has urgent broad-energy significance justifying the Letter format (not a fragment that should be a comprehensive Article); whether the format complies with the AAEM-specific length limits (300-word vs less than 100-word abstract; typically no more than 70 vs no more than 30 references);

whether the scope justifies AAEM rather than ACS Energy Letters (AAEM for materials-novel applied-energy with depth; ACS Energy Letters for time-sensitive broad-energy with breadth).

Manuscripts arriving with format-scope mismatch get redirected at editor triage with explicit format / venue recommendations.

Common patterns: Articles-shape work submitted as Letters that exceeds Letter length and gets redirected back to AAEM Articles or sometimes to ACS Energy Letters with the format-and-length expectations resolved; Letters-shape work submitted as Articles that does not have the depth justifying Article length and gets redirected to ACS Energy Letters or AAEM Letters; comprehensive materials work that lacks urgency submitted to ACS Energy Letters and redirected to AAEM Articles; urgent broad-energy work without materials novelty submitted to AAEM and redirected to ACS Energy Letters.

The fix is to decide format before drafting (Article = comprehensive materials-novel with full development; Letter = compact urgent contribution within strict length), match the abstract / reference / figure budget to the format from first draft, and choose between AAEM and ACS Energy Letters based on whether materials novelty (AAEM) or breadth-and-urgency (ACS Energy Letters) is the load-bearing element.

We reviewed the ACS Applied Energy Materials page on ACS Publications, the ACS AAEM Author Guidelines, the ACS Publishing Center, and ACS Journal Metrics. The cover-letter application requirement matches what ACS publishes; the routing reading and the seven desk-rejection patterns above are Manusights analysis and what authors report.

In our pre-submission review work for AAEM submissions, the stronger drafts made the named energy application, materials novelty, device-relevant operating conditions, TOC graphic, supporting information, data availability, and ACS portfolio routing visible before the editor had to infer the scope from results alone.

Source limitations: ACS official guidance explains the AAEM scope, article types, cover-letter requirement, and ACS Publishing Center workflow, but it does not publish manuscript-level desk decisions; the patterns above combine official guidance with anonymized Manusights pre-submission review work and public issue patterns.

Through our diagnostic review, we treat the cover letter, abstract, TOC graphic, device metrics, supporting information, and CCDC / structure files as one ACS Applied Energy Materials-facing package rather than as separate upload tasks.

Our analysis of recent ACS Applied Energy Materials issues focused on whether the manuscript's first figures, device metrics, supporting information, and cover letter make the energy application visible before the editor reaches the Results section.

The official checklist explains what to upload. The practical AAEM screen is whether the manuscript proves both halves of the title: applied energy and materials novelty. The review tells you whether your paper makes that two-part case before you commit the ACS Publishing Center package.

In our pre-submission review work we see a failure pattern that generic submit pages miss: AAEM-fit manuscripts can name an application in the cover letter but still fail when the figures do not show a device-relevant materials advance under realistic operating conditions.
