Document Type and Number:
WIPO Patent Application WO/2024/096273
Kind Code:
A1
Abstract:
The present invention relates to a method for producing lithium difluorophosphate in an economical manner. The method for producing lithium difluorophosphate does not use expensive reagents, enables lithium difluorophosphate having a high yield of 80% or more and a high purity of 99% or more to be produced in an economical manner through a simple method without complicated steps, does not require the additional addition of water since an aqueous hydrofluoric acid solution is added in a fixed amount, and does not use an excess amount of hydrofluoric acid gas, thus having the advantages of reducing the risk of production steps and reducing the step and risk of treating an excess amount of hydrofluoric acid gas after production.
