摘　　要：该文是一篇近两个月的锂电池文献评述,以“lithium”和“batter*”为关键词检索了Web of Science从2024年4月1日至2024年5月31日上线的锂电池研究论文,共有6423篇,选择其中100篇加以评论。正极材料方面主要研究了高镍三元、富锂正极材料的包覆和掺杂改性,以及其在高电压下所发生的表面和体相的结构演变。合金化储锂负极材料的研究侧重于复合电极结构设计和各类黏结剂的开发,以缓解循环过程中负极材料的体积变化,维持电极完整性。固态电解质的研究主要包括对现有固态电解质的合成、掺杂、结构设计、稳定性和相关性能研究以及对新型固态电解质的探索。其他电解液和添加剂的研究则主要包括不同电解质和溶剂对各类电池材料体系适配的研究,以及对新的功能性添加剂的探索。固态电池方向更多关注于复合正极设计、界面改性和影响锂枝晶生长的因素,出现了更多关于固态锂硫电池的研究论文。液体电解质电池技术偏重复合锂硫正极、锂硫电池“穿梭效应”的抑制、新电极制备技术以及锂界面枝晶及副反应抑制等。关于电池产热和气体成分、失效机制、热失控、界面稳定性的测量和分析论文也有多篇。This bimonthly review paper examines 100 recent studies on lithium batteries,selected from a pool of 6,423 papers published between April 1,2024 and May 31,2024 by searching through the Web of Science database.Research on layered oxide cathodes,including Ni-rich oxides and lithium-rich materials,is still under extensive investigations in terms of the modification of doping and coating.For the alloying mechanism of anode materials,beside the 3D structural design,many researchers pay attention to binders.Research on solid-state electrolytes primarily focuses on the synthesis,doping,structural design,and stability of pre-existing materials and development of new materials.Investigations into liquid electrolytes mainly concentrate on optimizing solvent and lithium salt compositions for various battery systems and testing new functional additives.While more studies related to solid-state Li-S batteries have been published,the design of composite cathodes and modification of solid-state battery interfaces continue to draw large attentions.Efforts in liquid-electrolyte Li-S batteries are mainly focused on improving S activity and mitigating the"shuttle effect."Additional research in liquid-electrolyte battery technology targets novel electrode fabrication methods and the suppression of dendrite formation and side reactions on lithium interfaces.The field also encompasses numerous studies on the measurement and analysis of battery heat production and gas composition,failure mechanisms,thermal runaway,interfacial stability,etc.
