ACS Energy Letters

ACS Energy Letters (commonly abbreviated as ACS Energy Lett.) is a peer-reviewed letters journal published by the American Chemical Society, founded in the United States in 2016, issued monthly and available in electronic form only. It addresses high-impact original work across energy conversion and storage, and is the rapid-publication energy title within the society portfolio.《美国化学会能源快报》（ACS Energy Letters，常用缩写为 ACS Energy Lett.）是由美国化学会出版的同行评审快报期刊，2016 年创刊于美国，月刊发行，仅以电子形式连续出版。该刊面向能源转换与存储诸方向的高影响原创工作，是美国化学会体系中以「快」为定位的能源类刊物。

Scope

ACS Energy Letters works from the premise that a conclusion in energy research should reach peers within weeks, and so takes only compact letters with clear-cut conclusions, leaving methodological detail to be developed later in full papers. Its principal subject areas include:ACS Energy Letters 的取稿立场是「能源研究的结论要在几周内到达同行手中」，因而只收篇幅紧凑、结论明确的快报，宁可把方法论细节留给后期的长文。收文范围覆盖的主要方向包括：

• Photovoltaics and optoelectronics: perovskite and organic solar cells, dye-sensitised and quantum dot devices, and device physics of novel light absorbers.光伏与光电器件： 钙钛矿与有机太阳能电池、染料敏化与量子点器件、新型光吸收材料的器件物理。
• Electrochemical storage: lithium-ion cells and solid electrolytes, lithium-sulfur and lithium-air batteries, and electrode chemistry of sodium and multivalent systems.电化学储能： 锂离子电池与固态电解质、锂硫与锂空电池、钠离子与多价离子体系的电极化学。
• Electrocatalysis and fuel cells: catalysts for hydrogen and oxygen evolution and carbon dioxide reduction, membrane electrode assemblies, and degradation mechanisms with operando characterisation.电催化与燃料电池： 析氢析氧与二氧化碳还原的电催化剂、燃料电池膜电极、催化剂衰减机理与原位表征。
• Solar fuels: photocatalytic water splitting and artificial photosynthesis, photoelectrochemical cell design, and records in solar-to-chemical conversion.太阳能燃料： 光催化分解水与人工光合作用、光电化学池设计、太阳能到化学能的转换效率记录。
• Supercapacitors and dielectrics: double-layer and pseudocapacitive materials, hybrid storage devices, and dielectric storage with self-powered systems.超级电容与电介质： 双电层与赝电容材料、混合型储能器件、介电储能与自供能系统。

Beyond letters proper, the journal runs perspectives, reviews and interviews to accommodate appraisal, survey and personal material, with the length ceiling for letters set separately in the author guidance.除快报本体外，本刊设观点、综述与访谈等栏目，用于安置评价性、综合性与人物性的内容；快报体裁的篇幅上限在投稿说明中另有规定。

History

• Founding (2016): the journal came online with volume 1 issue 1 on 8 July 2016, the society's first attempt at an electronic-only, letters-only format in energy.创刊（2016年）： 本刊于 2016 年 7 月 8 日以第 1 卷第 1 期上线，是学会在能源领域首次尝试纯电子、纯快报形态的刊物。
• Format rationale: energy research expanded rapidly through the 2010s while existing journals were too slow for first-to-report competition, and this title was created to shorten that lag.体裁定位： 能源研究在二十一世纪第二个十年迅速膨胀，而既有刊物的审稿周期难以容纳「先到先得」的成果竞争，本刊即为缩短这一时滞而设。
• Electronic publishing: no print edition has existed since launch, an unusual arrangement within the society at the time that later became common for new titles.电子出版： 本刊自创刊起即无印刷版本，仅以电子形式面世，此举在学会内部当时属少见安排，其后成为新创刊物的常见形态。
• Metric trend: the impact factor climbed quickly from 12.3 in 2017 to 24.0 in 2021 before easing to 17.5 in 2025, remaining in the upper band across physical chemistry, electrochemistry and energy fuels.指标走势： 影响因子自 2017 年的 12.3 快速爬升至 2021 年的 24.0，其后回落至 2025 年的 17.5，在物理化学、电化学与能源燃料三个类目中均保持上游。

Editors

An editor-in-chief leads a team structured around the two directions of storage and conversion, manuscripts arrive through the society's shared submission system, and the judgement of whether a paper carries the weight of a letter is made at triage. Neither the publisher nor the board publishes an acceptance rate or review duration for the title.本刊以主编为首组成编辑团队，下按存储与转化两大方向分设；稿件经学会统一的在线系统投递，编辑部对「是否够快报分量」的判断在初审即完成。出版方与编委会均未公布本刊的录用比例与审稿时长。

• Weight threshold: incremental work done merely for speed is filtered at triage, and only results judged to carry general illumination for the field are sent for review.分量门槛： 编辑部在初审阶段筛除「为快而快」的增量工作，只有被判为对该方向有普遍启发的结果才会送外审。
• Review pace: the letters format brings emphasis on turnaround, with referee reports normally returned within a few weeks, contrasting with most full-length titles from the same publisher.评审节奏： 本刊因快报定位而在流程上强调时限，评审意见通常在数周内返回，这与同出版方的大多数长文刊物形成对照。
• Relation to sister titles: journal overlaps in subject with the society's full-length energy title while complementing it in format, and manuscripts declined here are often advised to resubmit there.与姊妹刊的关系： 本刊与学会的能源类长文刊物在题材上相接而体裁上互补，被本刊退回的稿件常被告知改投后者。
