中文摘要: 通过基础热力学数据计算以及绘制反应体系的E-pH图,对废旧锂离子电池正极材料回收中钴铝同浸过程进行研究,考察了硫酸浓度、浸出时间、浸出温度、双氧水用量及液固比对钴、铝浸出率的影响。结果表明,在273 K,-0.277
Abstract:Through calculation of basic thermodynamics data and drawing of E-pH diagram of reaction system, the leaching process of recovery of cobalt and aluminum from spent lithium ion battery cathode materials was carried out. The effects of sulfuric acid concentration, leaching time, leaching temperature, hydrogen peroxide dosage and ratio of solid to liquid (L/S) on leaching rate of cobalt and aluminum were investigated. The results show that under the conditions including 273 K, -0.277
