From: Radiolysis as a solution for accelerated ageing studies of electrolytes in Lithium-ion batteries

Linear alkyl carbonates (diethylcarbonate, DEC, and dimethylcarbonate, DMC) and cyclic alkyl carbonates (propylene carbonate, PC, and ethylene carbonate, EC). DEC and DMC structures, written in bold, are studied here.
