The use of new energy such as clean energy, biomass and green hydrogen energy can eliminate carbon emissions at the source of industrial production. Wind energy and photovoltaic power generation are the future development pace, and energy storage materials such as lithium batteries are the "main force" supporting wind power generation. DODGEN combined with its own research and development and engineering advantages, devoted to synthesis and separation technology of lithium battery electrolyte (EC/DMC/VC/FEC), so the purity of 99.99~99.9999% ultra-pure electrolyte products can be obtained to meet the strict requirements of electronic chemicals.
