阅读说明：本技术 制备锂电池阴极的前体化合物的方法 (Method for preparing precursor compound of lithium battery cathode ) 是由 哈拉尔德·奥斯特胡夫 简·斯克叶尔 伦纳特·舍尔尼斯 巴尔特·克拉森 威利姆·卡勒波特 于 2020-04-17 设计创作，主要内容包括：本公开涉及用于锂电池阴极的前体化合物的生产。在还原条件下熔炼电池或其废料,从而形成适合进一步湿法冶金精炼的合金和熔渣。在酸性条件下浸提所述合金,产生载Ni和Co溶液,对其进行精炼。精炼步骤被大大简化,因为大多数易受所述精炼步骤干扰的元素集中在所述熔渣中。然后从所述溶液中沉淀出金属如Co、Ni和Mn,形成用于合成新电池前体化合物的合适的起始产物。(The present disclosure relates to the production of precursor compounds for lithium battery cathodes. Smelting the cell or its scrap under reducing conditions to form an alloy and a slag suitable for further hydrometallurgical refining. The alloy is leached under acidic conditions to produce a Ni and Co bearing solution, which is refined. The refining step is greatly simplified because most of the elements susceptible to interference by the refining step are concentrated in the slag. Metals such as Co, Ni and Mn are then precipitated from the solution to form suitable starting products for the synthesis of new battery precursor compounds.)
