Diethyl Carbonate (DEC)

Diethyl Carbonate (DEC) is a colorless liquid used as a solvent in the formulation of electrolytes for lithium-ion batteries. It plays a crucial role in forming the solid electrolyte interphase (SEI) layer on the anode surface, which enhances battery performance and safety. DEC is widely utilized in the electronics and automotive industries due to its excellent solvating power and compatibility with other electrolyte components.
