Upstream of the lithium ion battery industry chain need to complete the initial ore raw materials mining, smelting, chemical production and other processes, then, it transform the original minerals into secondary battery materials suitable for the production of power batteries, including positive materials, negative materials, electrolyte, battery separator, and other raw materials industries; The production and assembly of mid-stream lithium-ion batteries go through two steps: 1) a certain number of cells are assembled into battery modules in series and parallel; 2) Battery module, thermal management system, battery management system (BMS) and some structural parts constitute a complete battery PACK, also known as battery PACK; The main application fields of downstream lithium-ion batteries are new energy vehicle power batteries, consumer electronics and energy storage devices.
