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6月1日至2020年7月31日上线的锂电池研究论文,共有3632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、镍酸锂和高压钴酸锂的包覆和掺杂改性以及相关单晶材料的合成探索。硅基复合负极材料的研究侧重于优化电极结构以缓冲体积变化,金属锂负极的研究侧重于电极三维结构的构建。固态电解质的研究主要集中于新型固态电解质的探索以及对锂离子输运机理的理解,其他电解液方面主要涉及对溶剂、锂盐的调控优化以及对各类功能性添加剂的研究。固态电池和锂硫电池方向更多的关注于三维复合正极的设计开发。表征测试技术方面偏重于使用各种成像手段从多个尺度对电极内部微结构进行直观分析,且使用原位和非原位方法对电化学过程中各类性质的演变进行观测。此外,关于结构和界面模拟的理论计算工作也有多篇。

Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 3632 papers online from Jun. 1, 2020 to Jul. 31, 2020. 100 of them were selected to be highlighted. Layered oxide cathode including Ni-rich oxides and lithium cobalt oxide are still under extensive investigations for studying the influences of doping and coating on their electrochemical performances, and the synthesis of single-crystal materials. Large efforts were devoted to optimize and design the electrode structure of silicon-based and lithium metal anode materials, aiming to buffer detrimental volume change and regulate the deposition of Li. The researches of solid state electrolytes mainly focuses on developing new materials and understanding the mechanism of Li+ transport, while liquid electrolytes mainly focuses on the optimal design of solvents, lithium salts and development of different additives The researches that work on Solid-State battery and Lithium-Sulfur battery involve mainly the development of 3D composite cathode. The evolution of electrode microstructure and electrochemical properties are investigated by using in-situ and ex-situ technologies. There are a few papers related to the theoretical works, too.

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