[New Progress in Phase I of the 390,000 mt Electrolyte Solvent Project] The civil engineering main frames of various building units for a 390,000 mt/year electronic-grade carbonate new material project (Phase I: 170,000 mt/year) of an electrolyte solvent enterprise have nearly been completed, and the project has smoothly entered the crucial stage of core equipment installation. The total investment of this project is 1.55 billion yuan, covering an area of 94,387.67 m². Among them, Phase I of the project includes the construction of important production facilities such as a 100,000 mt/year electronic-grade ethyl methyl carbonate (EMC) production unit and a 20,000 mt/year electronic-grade diethyl carbonate (DEC) production unit. The main product, carbonate solvent, is applied as a solvent for lithium-ion battery electrolytes.
