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.

Diethyl carbonate

A linear carbonate solvent with a higher boiling point and viscosity than DMC, used in blends that must tolerate higher temperatures. Typical electrolytes mix EC with one or two of DMC, EMC and DEC.

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.
