| 摘 要： | 根据锂离子二次电池正极废料－铝钴膜原料中LiCoO2的性质，提出了LiCoO2在硫酸、双氧水体系中的分解反应为：2LiCoO2 3H2SO4 H2O2→Li2SO4 2CoSO4 4H2O O2↑确定从中回收铝、钴的工艺流程为：碱浸→酸溶→净化→沉钴。碱浸液中的铝用硫酸中和制取化学纯氢氧化铝，回收率94．84％；钴以草酸钴的形式回收，产品质量达到赣州钴钨有限责任公司的草酸钴产品标准，直收率95．75％。每处理1t铝钴膜废料可获纯利4．56万元。

| Abstract: | According to the property of LiCoO2 in Li-ion secondary batteryanode wastes of Al-Co film,dissolution reaction of LiCoO2 in a system of H2SO4 and H2O2 was put forward:2LiCoO2+3H2SO4+H2O2→Li2SO4+2CoSO4+4H2O+O2↑A simple process for recycling cobalt and aluminum was determined,including alkali leaching of wastes,acid dissolution of slag,purification of cobalt-containing solution and precipitation of cobalt.The recovery of cobalt reaches 95.75%.Aluminum in alkali leaching solution was neutralized with H2SO4 and the product Al(OH)3with a chemical purity was obtained,the recycling rate is 94.84%.The profit of 45600.6 RMB Yuan can be obtained in treating l ton waste by the technology. |
