Abstract: Electrolyte is a key component of the lithium-ion battery. The basic function of electrolytes is to serve as the medium for the transport of lithium ions between the electrodes. The chemical composition of electrolytes has a direct influence on the characteristics of LIBs, such as energy density, cycleability, rate capability, storage performance and safety. After more than ten years of rapid development, China’s electrolyte industry has obtained the ability to compete in the global market. In this review, the development of the electrolyte industry, as well as the domestic market status are briefly summarized. Taking the patent ownership of commonly used electrolyte additives as an example, the differences in the patent applications of between domestic and foreign major enterprises are analysed. The characteristics of four types of electrolyte products, which are used for 3C batteries, xEV batteries, energy storage batteries and functional batteries respectively, are introduced. The design ideas of the former two types of products are emphasized. China’s industry standards of LIB-used electrolytes are also mentioned. The technical trend and industry prospect of commercial electrolytes are discussed.
