摘要

分别采用盐酸-30%过氧化氢、硫酸-30%过氧化氢和硝酸-30%过氧化氢为浸取液

回收锂离子电池正极材料中的金属钴

研究了浓度、温度、30%过氧化氢的量、反应时间、固-液比等对钴浸取率的影响.经响应面分析实验结果表明

盐酸-30%过氧化氢最适宜做浸取液

最佳工艺条件为:盐酸浓度为4.0 mol/L

盐酸-30%过氧化氢体积比为5∶1

反应时间61 min

反应温度73℃

固-液比(g/mL)为1∶30.3

在此条件下

Co2+浸出率达到99.8%.

Abstract

The metal cobalt in lithium-ion battery cathode material is recycled by hydrochloric acid-hydrogen peroxide

sulfuric acid-hydrogen peroxide and nitric acid-hydrogen peroxide as the leaching solution

respectively.The influences of concentration

temperature

amount of hydrogen peroxide

reaction time

solid-liquid ratio on leaching efficiency of cobalt ion are studied.Experimental results have shown that the hydrochloric acid-hydrogen peroxide system is the most appropriate leaching solution.The optimum process ...
