摘要

Abstract

With the development of digital products

electric vehicles and energy storage technology

electronic chemicals play an increasingly prominent role in the field of new energy such as lithium-ion batteries. Electronic chemicals have attracted extensive attention in various fields. Characteristics of high-end electronic chemicals are high purity and low impurity content

which requires a very strict separation and purification process. At present

crystallization is a key technology for their separation and purification of electronic chemicals. In this work

the representative fluorine-containing compounds in cathode and anode materials

separator and electrolyte of lithium-ion batteries are introduced. The latest technologies for the preparation and purification of four kinds of fluorine-containing battery chemicals by crystallization technology are reviewed. In addition

the research prospects and suggestions are put forward for the separation of fluorine-containing battery chemicals.
