What is lithium battery anode material？
Lithium battery anode material: graphite is the mainstream anode material, and local enterprises are in the first echelon
Lithium-ion batteries refer to secondary batteries with lithium intercalation compounds as positive and negative materials. During the charging and discharging process, lithium ions are deintercalated and intercalated back and forth between the two electrodes. Compared with traditional lead-acid batteries and nickel-chromium batteries, lithium-ion batteries have the advantages of high energy density, long cycle life, good charge and discharge performance, high operating voltage, no memory effect, less pollution and high safety. Similar to fuel cells, air batteries and super capacitor batteries, lithium-ion battery technology is obviously mature.
Negative materials are generally divided into carbon-based negative electrodes and non-carbon-based negative electrodes. Among them, carbon-based negative electrodes can be divided into graphite, hard carbon, and soft carbon negative electrodes. Graphite can be divided into artificial graphite, natural graphite, and mesocarbon microspheres; non-carbon The negative electrode includes lithium titanate, tin-based alloy negative electrode, silicon-based alloy negative electrode, and the like.
At present, the mainstream anode products include natural graphite and artificial graphite. Artificial graphite is mainly used for high-capacity vehicle power batteries and rate batteries, as well as lithium-ion batteries for mid-to-high-end electronic products. Natural graphite is mainly used for small lithium-ion batteries and general-purpose batteries. electronics lithium-ion batteries.
Graphite materials will still have the advantages of technology, price and mature supporting facilities in the next few years. Graphite as a negative electrode material will remain the mainstream in the next few years, and plays a very important role in the performance and safety of lithium-ion batteries. At present, the development direction of lithium-ion batteries is high capacity, high rate, and high safety. The main way to achieve high capacity and high rate is to develop high-performance lithium-ion battery anode materials with artificial graphite as the main raw material.
Anode material industry chain
Anode material industry chain: upstream of lithium battery anode materials, raw materials vary according to different product types. The upstream raw materials of natural graphite anode materials are natural graphite ore, and the upstream raw materials of artificial graphite anode materials are needle coke, petroleum coke, pitch coke, etc. ; Lithium battery anode material equipment mainly includes fluidized bed, rotary furnace, etc.
The midstream of lithium battery anode materials is the production and processor of lithium battery anode materials, producing different types of anode materials. The downstream of lithium battery anode materials is the lithium battery industry, and the products of the downstream industry are finally used in three major fields: power batteries, 3C consumer batteries and industrial energy storage batteries. The downstream industry has a great impact on the development of the anode material industry, and changes in its demand directly affect the future development of the anode material industry.
