Analysis and Exploration of the Process for Preparing Lithium Hydroxide Monohydrate from Recycled Lithium Carbonate from Batteries
The recovery of lithium is a crucial step in battery recycling.Currently,wet leaching technology is commonly employed to extract valuable elements from the black powder.This process involves impurity removal and purification,resul-ting in a refined lithium sulfate solution.Carbonic acid is subsequently added.Sodium is used to produce either industrial-grade lithium carbonate or crude lithium carbonate.The resulting lithium carbonate undergoes further refinement to remove impurities,creating a product suitable for battery production.Given the growing demand in the lithium hydroxide market,the cost-effective and efficient conversion of lithium carbonate to lithium hydroxide has become increasingly important.This study centers on the conversion process,transforming lithium carbonate obtained from battery recycling into lithium hydrox-ide.The analysis covers critical factors,including raw material selection,process routes,product and byproduct yields,and energy consumption across various process options.Through a comparison of advantages and disadvantages,suitable process routes for different company states were summarized,aims to offer valuable insights for optimizing production and adding val-ue to the recycling industry chain.This study can serve as guidance for battery recycling companies when choosing lithium hydroxide production methods.Furthermore,it serves as a reference for producing lithium hydroxide from lithium carbonate obtained via extraction from salt lakes and ores.
