摘要: 该文是一篇近两个月的锂电池文献评述,我们以“lithium”和“batter*”为关键词检索了Web of Science从2017年6月1日至2017年7月31日上线的锂电池研究论文,共有1961篇,选择其中100篇加以评论。正极材料主要研究了层状、尖晶石和磷酸盐正极材料的结构演变以及表面包覆和掺杂对它们的循环寿命和热稳定性的影响。高容量的硅、锡基负极材料侧重于研究材料合成和应用条件与循环性能的关系以及容量随循环损失的机理。金属锂负极的研究侧重于通过集流体和表面覆盖层的设计来提高其循环性能。固态电解质方面制备方法和界面修饰是研究重点,电解液添加剂的研究目标是提高电池的高温稳定性。锂空电池、锂硫电池侧重于改进电池的循环性能。理论模拟工作包括材料体相、界面结构和输运性质,除了以材料为主的研究之外,针对电池的原位分析的研究论文也有多篇。

Abstract: This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 1961 papers online from Jun. 1, 2017 to Jul. 31, 2017. 100 of them were selected to be highlighted. Layered oxide and spinel cathode materials are still under extensive investigations for the effects of structure evolution and modificationson their cycling property and thermal stability. Large efforts were devoted to Si and Si based anode material for improving their cycling propeties with new preparation method and optimal working conditions. Their capacity fading mechnism is also analyzed. The cycling properties of metallic lithium electrode are improved by designing current collector and surface cover layer. The studies of solid state electrolytes are focus on the method of preparation and interface modification. Additives to liquid electrolyte can help to improve the cell’s stability at elavated temperatures. There are a few papers related to Li/S battery, Li-air battery for improving their cycling performance and more papers related to cell analyses, theoretical simulations, and modeling.

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