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2022年8月1日至2022年9月30日上线的锂电池研究论文,共有4656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、高电压钴酸锂和镍锰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包括材料制备和对电极结构的优化以缓冲体积变化,并重点关注了功能性黏结剂的应用。金属锂负极的研究包含金属锂的表面修饰和三维结构设计。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。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正极中离子、电子传输能力的提升。锂硫电池的研究重点是提高硫正极的活性,抑制“穿梭”效应。电池技术方面的研究还包括电极结构设计和人造SEI层的构建。测试技术涵盖了锂沉积、硅负极演化和三元正极产气等方面。理论模拟工作侧重于固态电池中固体电解质及其与电极界面的稳定性研究。

Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 4656 papers online from Aug. 1, 2022 to Sept. 31, 2022. 100 of them were selected to be highlighted. High-nickel ternary layered, high-voltage LCO layered and LNMO spinel cathode materials are still under extensive investigations of the influences of doping and interface modifications on their electrochemical performances and surface and bulk evolution of structures under prolong cycling. For alloying mechanism anode materials, such as silicon-based composite materials, many researchers pay attention to material preparation and optimization of electrode structure to buffer volume changes, and emphasize the application of functional binders. Large efforts were devoted to design the three-dimensional structure electrode, interface modification, and inhomogeneity plating of lithium metal anode. The researches of solid-state electrolytes are mainly focused on synthesis, doping, structure design and stability of pre-existing materials and developing new materials, whereas liquid electrolytes are improved by the optimal design of solvents and lithium salts for different battery systems and adding different additives. For solid-state batteries, the studies are mainly focused on the improvement of ionic and electronic conductivity in cathodes. To suppress the "shuttle effect" of Li-S battery, composite sulfur cathode with high ion/electron conductive matrix and functional binders are studied. Other relevant works are also presented to the design of electrode structure and manufactural SEI. There are a few papers for the characterization techniques are on lithium deposition, volume change of silicon-based anode materials and oxygen release of ternary layered materials. Furthermore, theoretical calculations are done to understand the stability of solid electrolytes and the interface of solid state electrolyte/Li.

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