4-methyl-1,3,2-dioxathiane 2-oxide is mainly used as an additive in lithium-ion batteries. Its total potential energy and LUMO value are lower than those of propylene carbonate (PC), giving it a stronger electron-accepting ability and making it less susceptible to oxidation. When used as an additive in lithium-ion batteries in combination with propylene carbonate (PC), it effectively suppresses the co-intercalation of PC in graphite electrodes, providing better electrode protection, significantly improving the internal cycle performance of lithium batteries, and extending battery life. |
