An electrolyte solvent is an organic liquid that dissolves lithium salts and enables the movement of lithium ions in a lithium-ion secondary battery.
There are two types of electrolyte solvents: cyclic carbonate solvents and chain carbonate solvents.
Cyclic carbonate solvents are composed of EC (ethylene carbonate) and PC (propylene carbonate),
Chain carbonate solvents are composed of EMC (ethyl methyl carbonate), DMC (dimethyl carbonate), DEC (diethyl carbonate), etc.
In this column, we will introduce the production methods of carbonate-based solvents, which are used as the main solvent for the electrolyte of lithium-ion secondary batteries.
