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2013年2月1日至2013年3月31日上线的锂电池研究论文,共有924篇,选择其中100篇加以评论.层状氧化物、高压尖晶石和聚阴离子正极材料继续受到关注.高容量的 Si 基负极材料一直是研究的热点,然而其体积膨胀、长循环效率低的缺点尚未被克服.本期有多篇电解液添加剂的研究论文给出了较好的结果.具有高能量密度的Li-O2和Li-S电池仍是研究热点.除了这些以材料为主的研究之外,有多篇涉及电池预期寿命估计和电池失效机理分析的论文,还有一个特点是SEI形成机理和电池内部应力分析的理论计算论文开始多起来.

This bimonthly review paper highlights 100 recent publications on lithium batteries. These papers were selected from 924 contributions found from the Web of Science between 1 February 2013 and 31 March 2013. Layered oxide cathode materials, high voltage spinel and polyanion are still under extensive investigations. Significant efforts have been devoted to Si based anode materials although the well known drawbacks of volume expansion and low Coulombic efficiency of the materials have not been overcome.. Several papers have shown positive results for different electrolyte additives. Li-O2 and Li-S batteries with high energy density are found to the hot topic in the field. There are several papers on the SOH estimation and the degradation mechanisms of Li-ion batteries. There are also reports on calculations for electrode materials, SEI formation process and stress generation in the cells.
