Abstract

A disposal technology for lithium batteries with minimal environmental impact is proposed. Ground battery components are processed in five stages, to produce mechanically activated powder. Attention focuses on two stages: leaching; and purification and concentration of the lithium hydroxide and carbonate in a high-pressure membrane unit. Theoretical principles are outlined for mechanical–chemical destruction of the ground battery components with high product yield. Analysis of ball and product motion in a ball mill shows that waterfall motion of the balls is optimal. Formulas are given for the equivalent diameter of the particles and their specific surface.

用过的锂电池生产氢氧化锂和碳酸锂

摘要

提出了一种对环境影响最小的锂电池处理技术。接地电池组件分五个阶段进行处理，以产生机械活化的粉末。注意集中在两个阶段：浸出；高压膜单元中氢氧化锂和碳酸盐的纯化和浓缩。概述了用于以化学方式销毁具有高成品率的接地电池组件的理论原理。在球磨机中对球和产品运动的分析表明，球的瀑布运动是最佳的。给出了当量粒径及其比表面积的公式。
