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2019年4月1日至2019年5月31日上线的锂电池研究论文,共有2969篇,选择其中100篇加以评论。正极材料主要研究了层状三元材料、富锂相材料和尖晶石材料的结构和表面结构随电化学脱嵌锂变化以及掺杂和表面包覆及界面层改进对其循环寿命的影响。硅基复合负极材料研究侧重于复合材料、电极结构和电解液添加剂改进,金属锂负极的研究侧重于通过表面覆盖层的设计来提高其循环性能。固体电解质重点研究硫化物和含卤素的硫化物,固态电池的研究也多数选用硫化物固体电解质。电解液添加剂则重点在于提升高电压和高镍电解质循环稳定性和充放电库伦效率。锂硫电池的研究侧重于正极的改进。原位分析偏重于电极中的反应和固态电池的失效过程。理论模拟工作涵盖动力学、界面SEI形成机理分析和电池失效机制等。

Abstract: This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 2969 papers online from Apr. 01, 2019 to May 31, 2019. 100 of them were selected to be highlighted. Layered oxide including Li-rich oxides and high voltage spinel cathode materials are still under extensive investigations for studying Li+ intercalationdeintercalation mechanism and evolution of surface structure, and the influences of doping, coating and interface modifications on their cycling performances. Large efforts were devoted to Si based composite anode materials for optimizing the composite material, electrode and electrolyte. The cycling properties of metallic lithium electrode are improved by using different kinds of surface cover layer. Sulfde and halide containing sulfde based solid state electrolyte and solid state batteries are drawn large attentions. Additives to liquid electrolytes are investigated for improving the cycling performance and coulombic efficiency of high voltage spinel and Ni-rich oxide cathodes. The cathode of Li-S battery is investigated for optimizing its kinetic and cycling performances. In-situ technologies are used to analyze the structural evolution of cathode materials and the fading of solid state batteries and theoretical work covers the kinetics, SEI, the cell fading mechanism.

Key words: lithium batteries, cathode material, anode material, electrolyte, battery technology
