Carbonate solvent

The organic liquids that dissolve the lithium salt: cyclic ethylene carbonate, which forms a stable SEI, blended with linear carbonates such as DMC or EMC to lower viscosity. All are flammable, which is a root of lithium-ion fire risk.

Dimethyl carbonate

A linear carbonate solvent, thin and volatile, blended with EC to cut viscosity and raise ionic conductivity. Its low boiling point, about 90 °C, is part of why cell electrolytes are flammable.

Ethylene carbonate

The cyclic carbonate solvent that every graphite cell needs: it is reduced on the first charge into the stable SEI that lets graphite work at all. It is solid at room temperature, so it is always blended with linear carbonates.

Ethyl methyl carbonate

A linear carbonate solvent, the most common co-solvent in commercial electrolytes, balancing viscosity, boiling point and low-temperature performance between DMC and DEC.
