Abstract

Abstract:

Cobalt sulfate is the raw material of the ternary lithium battery.Currently,the cobalt sulfate particles in the market are pretty small,and there is a problem of easy agglomeration,which is inconvenient for the customer to use.The two processes of intermittent production and continuous production of cobalt sulfate crystal were compared.The control factors of the production process of large particle cobalt sulfate crystal were introduced,and the problems of OSLO crystallizer in the production of large particle cobalt sulfate crystal were emphasized.The main process control points in production were described,which provided a theoretical basis for the production of large-particle cobalt sulfate crystals,and the market trend of cobalt sulfate crystals was forecasted.

Key words: cobalt sulfate, ternary lithium battery, intermittent production, continuous production

TQ138.12
