The Purification of Organic Solvent in Li Cell and Its Effect

本文研究了碳酸丙烯酯(PC)、四氢呋喃(THF)、1,2-二甲氧基乙烷(DME)和γ-丁内酯(BL)的纯化及其去水效果。实验表明:本文所述纯化试剂方法,去水效果明显。

Studies on Li cell have made great progress these years,which brings study and use of organic electrolyte solutions.In the development and use of the cell,people show great interest in the purification of the solvents which make the electrolytic solutions,and its effect.Because of the chemical specific property of Li,people pay close attention to removing water from the solvents.The propylene carbonate(PC),1,2-dimethoxyethene(DME),tetradrofuran(THF)and 4-butyrolactone(BL)are usually used as solvent to prepare electrolyte solution for Li cell.This paper is about the study on purification of organic solvent and its effect.Experiments show that the means of purification in the paper may produce good effect of removing water.
