二次锂电池进展

Recent Progress in Lithium Ion Rechargeable Battery

本文叙述了二次锂电池的开发现状、存在问题及解决途径。表述了二次锂离子电池的概貌及特点,该电池以碳为负极,能有效地避免充电时锂枝晶引起的短路,改善了循环寿命,提高了能量密度,有利于电池小型化。

A review with 12 references was give on the status of the research and development of lithium ion secondary cells. The brief introduction and main characteristics of this battery were outlined. Carbon was used as negative electrode and could effectively prevent the dendritic deposition of lithium metal from causing the internal short circuit when the battery was charging. So the cycle life and energy density of this battery were significantly improved and the miniaturization could be realized.
