The Negative-Electrode Material Electrochemistry for the Li-Ion Battery

摘要:

二次锂电池的优点是高体积、高质量比容量、长循环寿命、低自放电速率，是环保型电动车驱动电源的理想候选之一。二次锂电池负极材料经历了第1代的金属锂、第2代的碳材料，即石墨嵌入化合物GIC，目前研究的焦点是锂合金负极材料。本文在总结了金属锂和碳材料的同时，综述了3年来负极锂合金材料的研究状况。

Abstract:

The rechargeable lithium ion battery has been extensively used in mobile communication and portable instruments due to its many advantages, such as high volumetric and gravimetric energy density, long cycle life, low self-discharge rate. In addition, it is the promising candidate as the power source for electric vehicles. The first generation of negative electrode materials was pure lithium metal; the second was carbon. Nowadays extensive research is focusing on lithium alloys. In this paper, the properties of lithium metal and carbon are summarized and the development of lithium alloys is reviewed.
