Approach to optimization of electrolyte production process

doi:10.12028/j.issn.2095-4239.2018.0081

Abstract

Abstract: Based on the rapid rise of lithium industry, the market demand of lithium ion battery electrolyte is expanding, and the traditional electrolyte production process can not meet the existing development needs. It is particularly important to seek new ways to optimize the process and combine traditional production technology to further improve the production capacity and quality of the electrolyte. On how to improve production efficiency, shorten production cycle and reduce energy consumption, further analysis and discussion are made on the basis of experience and experimental results in practical application.

Key words: electrolyte, optimization way, production process
