According to the division of the production and application of lithium batteries, the lithium battery industry chain can be roughly divided into the following four parts.

　　1. Upstream industry-mining resources

　　The upstream industry of lithium batteries is mainly composed of natural mineral resources, including cobalt, nickel, manganese, phosphorus, iron, lithium and various compounds. Among them, cobalt and lithium, which have limited reserves in nature, are used the most.

　　2. Midstream industry-the core of the material link

　　Material research and development is the core link of the lithium battery industry chain, which determines the technological progress of lithium batteries. Among them, the cathode material with the largest market capacity and higher added value is the cathode material, which accounts for about 30% of the cost of lithium batteries. Lithium iron phosphate materials are currently the most promising in the industry. Lithium iron phosphate battery packs are smaller in size and lighter in weight; long service life, good high temperature performance, fast charging, safe and stable, green and environmentally friendly, and no memory effect.

　　3. Midstream industry-scale and branding of assembly

　　The middle link of the lithium battery industry chain is battery cell manufacturing and PACK assembly, which is a labor-intensive large-scale manufacturing industry.

　　4. Downstream industry-end customer application scenarios

　　The downstream of the lithium battery industry chain refers to the application links, including mobile phones, laptops, digital cameras, power tools, miner’s lamp markets, wind power generation systems, photovoltaic energy storage systems, data center systems, UPS systems, electric bicycles, electric motorcycles, and electric mobility Cars, electric wheelchairs, electric cars, electric golf carts, etc.

　　In the military and aerospace fields, such as tanks, submarines, rockets, lunar rover and so on.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect substitute for lead-acid batteries and are the first choice in the energy storage industry.
