Methyl phenyl carbonate (commonly designated as MPC) is an asymmetric aromatic-aliphatic organic carbonate engineered as a specialized functional electrolyte additive for advanced lithium-ion batteries. By pairing a traditional methyl group with an electron-withdrawing phenyl ester group, MPC acts as a sacrificial film-forming agent tailored to enhance high-voltage operational stability and interfacial passivation.
Its functional roles in electrolyte engineering are: (1) Sacrificial Cathode-Electrolyte Interphase (CEI) Formation: MPC exhibits a tailored oxidation potential that allows it to participate in preferential, sacrificial electrochemical oxidation during early-stage charging cycles, creating a protective, passivating film on the positive electrode surface before bulk solvent degradation occurs. (2) Mitigation of Parasitic High-Voltage Reactions: The presence of the aromatic phenyl group alters the electronic structure around the carbonate core, helping suppress oxidative electrolyte decomposition, transition-metal dissolution, and gas generation at upper cut-off potentials. (3) Interfacial Resistance and Stability Balance: When deployed at optimized thresholds, MPC constructs a thin, stable interphase that prevents continuous electrolyte consumption while maintaining low overall cell impedance during extended cycling.
