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2020年4月1日至2020年5月31日上线的锂电池研究论文,共有3260篇,选择其中100篇加以评论。正极材料的研究主要集中在对高镍三元和高压钴酸锂的表面改性和体相掺杂,以及其在长循环过程中或高电压下所发生的表面和体相的结构演变。硅基复合负极材料的研究侧重于对电极结构的设计,金属锂负极的研究侧重于通过电极结构的设计来调控SEI的生长以及抑制锂枝晶的形成。固态电解质的研究主要包括对氧化物固态电解质、硫化物固态电解质、聚合物固态电解质以及复合固态电解质的结构设计以及相关性能研究。液态电解液方面主要涉及对溶剂、锂盐以及添加剂的选择优化设计。固态电池、锂硫电池的论文也有多篇。测试技术方面偏重于用原位方法对材料结构的演变以及SEI的生长等进行观测和分析,同时也有多篇涉及到对电池热失控的研究。此外,还有多篇论文用理论计算对材料的电子结构以及锂离子的输运和沉积进行了探讨。This bimonthly review paper highlights 100 recent published papers on lithium batteries.We searched the Web of Science and found 3260 papers online from Apr.01,2020 to May 31,2020.100 of them were selected to be highlighted.Layered oxide cathode materials are still under extensive investigations for studying Li+intercalation-deintercalation mechanism and evolution of structure,and the influences of doping and interface modifications on their electrochemical performances.The researches of silicon-based composite anode materials mainly focuses on the design of electrode structure,while the researches of lithium metal anode mainly focuses on the design of electrode structure and further to regulate the growth of SEI and inhibit the formation of lithium dendrites.Large efforts were devoted to solid state electrolytes including oxide,sulfide,polymer and composite solid state electrolytes.The research works on liquid electrolytes involves mainly the optimal design of solvents,lithium salts and additives.The structure evolution of materials and the growth of SEI are investigated by using in-situ technologies.Furthermore,there are a few papers related to the theoretical works for the electric structure of materials,Li+transport and Li metal deposition.
