对废旧锂离子电池正极材料的资源化利用
不仅保护了环境
而且具有明显的经济效益。采用全湿法流程回收废旧锂离子电池中的钴和锂
用溶剂萃取法除杂和分离钴、锂
使得钴回收率高达99%以上。废电池中主要元素钴、铝、锂都有无害于环境的安全出路
不产生二次污染。
Abstract
The cobalt content is up to 40%

5% in cathode material of the lithium batteries
The recycling of cathode materials for waste lithium-ion batteries not only protects the environment but also has obvious economic benefits. The cobalt and lithium of waste lithium-ion batteries are recycled through the all-wet process. The recovery rate of cobalt is more than99% by solvent extraction to remove impurities and separate of cobalt and lithium. The main elements of lithium
cobalt and aluminum in waste lithium-ion batteries can be safely recycled and don’t produce secondary pollution.
