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6月1日至2019年7月31日上线的锂电池研究论文,共有3486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和钴酸锂材料的掺杂表面包覆对其性能的改善作用。硅基负极材料和金属锂负极侧重于设计三维结构、表面修饰和使用功能电解液添加剂来提高循环性能和库仑效率。固体电解质研究集中在硫化物、含卤素的硫化物和聚合物,电解液侧重于研究提高正极表面CEI稳定性的和抑制正极溶解的过渡金属离子对负极SEI稳定性影响的功能添加剂。固态电池的研究主要为固态锂电池和锂离子电池正负极的复合电极设计。锂硫电池的研究重点在于正极的催化活性研究和负极界面的稳定性研究。原位分析偏重于锂离子和固态锂二次电池的失效机制分析。还有少数几篇涉及理论计算和电池回收。

Abstract: This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 3486 papers online from Jun. 1, 2019 to Jul. 31, 2019.100 of them were selected to be highlighted. Layered oxide including Ni-rich oxides and lithium cobalt oxide are still under extensive investigations for studying the influences of doping and coating on their cycling performances. Large efforts were devoted to improve the cycling performance and coulombic efficiency of Si based and metallic lithium anode by optimizing their 3D electrode structure, surface and electrolyte. Sulfide, halide containing sulfide and polymer based solid state electrolyte are drawn large attentions. Additives are added to liquid electrolyte to form stable CEI and reduce the effects of the dissolved transition metal ions from the cathode to SEI at the anode. The studies of solid state battery are focus on the designs of composite electrode and 3D structure for both cathode and anode, so as to the Li-S battery. In-situ ex-situ technologies are used to analyze the fading mechanism of Liion battery and solid state lithium battery. There are few papers related to theoretical calculations and recycling of lithium ion batteries, too.

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