Solvent is another key component of the electrolyte, accounting for about 80% of the overall proportion of the electrolyte. Carbonate ester products are the main raw materials for lithium battery electrolytes and are currently the mainstream electrolyte solvent. The commonly used solvents can be roughly divided into the following categories: carbonates, sulfites, and sulfones. Carbonate ester products are currently the most widely used electrolyte solvents due to their comprehensive advantages in performance and cost. Therefore, the current electrolyte solvent is mainly a mixture of various carbonates, including dimethyl carbonate, diethyl carbonate, ethylene carbonate, propylene carbonate, and methyl ethyl carbonate. Among them, dimethyl carbonate has the largest amount and is one of the most widely used electrolytes.
Our company adopts the internationally advanced methanol gas-phase oxidation carbonylation production process, which has advantages such as higher product purity, more stable quality, and lowest production cost. It can ensure the longer endurance of lithium batteries under low temperature conditions and is in an absolute leading position in China. The specific indicators are as follows:
