退役钴酸锂电池材料回收利用研究趋势

Trend of Research on Recycle of Used LiCoO_(2) Batteries

随着智能电子终端普及与"5G时代"来临,废旧钴酸锂锂离子电池产量已逐年增加。废旧钴酸锂电池中蕴含丰富钴资源,是缓解我国钴供需紧张的重要源头,废旧LiCoO_(2)电池资源化利用具有重大的现实意义。为此,本文介绍近年来废旧钴酸锂电池材料回收利用研究现状,分析废旧钴酸锂电池常用回收利用方法优缺点,主要包括火法回收、湿法回收和材料再生等方案,并评述废旧钴酸锂电池材料回收利用研究发展趋势。

With the popularization of intelligent terminals and the coming of“5G era”,the quantity of used LiCoO_(2)batteries has been increasing year by year.Due to its rich Co content,used LiCoO_(2)battery is an important source to ease the tight supply of Co in China.Thus,its recycle is of great practical sig-nificance.In this paper,the status quo of study on the recycle of used LiCoO_(2)batteries is introduced,and the recycling methods are analyzed from the respects of advantages and disadvantages.These methods mainly include pyrogenic process,wet process,material regeneration,etc.Moreover,the research and development trends of recycling used LiCoO_(2)batteries are discussed.
