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12月1日至2021年1月31日上线的锂电池研究论文,共有3193篇,选择其中100篇加以评论。层状正极材料的研究集中在高镍三元材料和富锂相材料,其相关研究关注表面包覆层、前驱体及合成条件、循环中的结构变化。硅基复合负极材料的研究重点包括对硅颗粒的包覆,具有三维结构的硅/碳、硅/铜复合电极。碳负极及金属锂负极,尤其是金属锂负极界面及三维结构设计,同样是受重点关注的研究对象。固态电解质的研究主要包括对硫化物固态电解质、氧化物固态电解质、聚合物与氧化物固体电解质复合材料的合成以及相关性能研究。液态电解液方面包括提升石墨负极的性能,及适应高电压镍锰酸锂、三元层状材料、钴酸锂、富锂材料等正极材料电池的添加剂研究。针对固态电池,复合正极制备、双层电解质结构、锂金属界面修饰等都是主要研究内容,其他电池技术主要偏重方面还有三维结构锂硫正极设计,导电添加剂对正负极的影响等。表征分析涵盖了金属锂沉积过程、硅负极的体积膨胀问题、正极微结构和电池气胀问题。理论模拟工作涉及SEI形成机制以及厚电极电池的动力学,界面问题涉及层状正极固液态电池界面、液态电解质负极电极、固态电解质与Li界面等。

Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 3193 papers online from Dec 1, 2020 to Jan 31, 2021. 100 of them were selected to be highlighted. High-nickel ternary layered and Li-rich oxide cathode materials are still under extensive investigations for surface coating, preparation of precursors and structural evolution with cycling. The methods for improving the cycling properties of Si-based anode focus on coating Si particles and 3D structure design of the composite Si/C and Si/Cu anodes, while 3D structure design and surface reconstruction are used for metallic lithium anode. Solid state electrolyte including oxide, sulfide and composite materials have been studied. Meanwhile, large efforts are still devoted to liquid electrolytes for the optimizing the electrolyte for graphite anode, the high-voltage spinel and LiCoO2, ternary layered, and Li-rich oxide cathode materials. For solid-state batteries, there are a few papers related to the design of composite cathode, bi-layer electrolyte, and modification of Li metal anodes. Other relevant works are also presented to the 3D structure design of S-based cathodes and the effects of electron-conductive additives in to electrodes. The characterization techniques are focused on Li deposition, swelling of Si-based anode, micostructures of cathodes and gassing of cells. Theoretical simulations is mainly on the formation mechanism of SEI and kinetics of thick electrodes. The interfaces of layered cathode and solid/liquid electrolyte, liquid electrolyte/anode, and solid state electrolyte/Li are also widely studied.

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