The short-path molecular distillation system of YHChem Technology has demonstrated significant advantages in the purification of electrolyte solvents
Process features
Practical application cases A well-known electrolyte manufacturer has adopted the YMD-10S short-path molecular distillation system of YHChem Technology for the refining of dimethyl carbonate (DMC). The processing capacity of this system reaches 80kg/h, increasing the purity of DMC from 98.5% to 99.95% and reducing the moisture content to below 10ppm, significantly enhancing the electrochemical performance of the electrolyte.
Lithium hexafluorophosphate (LiPF6) is the most important lithium salt in the electrolyte. Its synthesis involves the reaction of hydrogen fluoride and diphosphorus pentoxide. During the process, the reaction conditions need to be strictly controlled to avoid the occurrence of side reactions.
