Manufacturers of anode materials for lithium batteries
Who are the manufacturers of anode materials for lithium batteries? There are more and more manufacturers of lithium battery anode materials. The anode material mainly affects the first efficiency and cycle performance of lithium batteries. The performance of the anode material also directly affects the performance of the lithium battery. The anode material accounts for about 5 to 15% of the total cost of the lithium battery. It plays a vital role in the final performance of new energy vehicles. What are the anode materials for lithium batteries? Lithium battery anode materials are roughly divided into six types: carbon anode materials, alloy anode materials, tin-based anode materials, lithium-containing transition metal nitride anode materials, nano-level materials, and nano-anode materials. The first is the anode material of carbon nano-materials: the anode materials that have been actually used in lithium-ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, and pyrolysis. Resin carbon, etc. The second type is alloy-based anode materials: including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys. There are currently no commercial products. The third type is tin-based anode materials: tin-based anode materials can be divided into tin oxides and tin-based composite oxides. Oxide refers to the oxide of tin metal in various valence states. There are currently no commercial products. The fourth type is lithium-containing transition metal nitride anode materials, and there are currently no commercial products. The fifth type is nano-scale materials: carbon nanotubes, nano-alloy materials. The sixth nano-anode material: nano-oxide material.

Lian Hongguang’s main products include natural graphite, artificial graphite, composite graphite, mesophase, power materials, etc. It has two production bases in Dalian and Dandong, with an annual production capacity of 4,000 tons. Main customers BYD and BAK batteries, etc. In the first half of 2017, the sales volume of anode materials for lithium batteries was approximately 1,500 tons. Dalian Hongguang focuses on the production of power graphite anode materials, and has established a new material research institute, a material testing institute, a power material research institute, a graphitization research institute, etc., and has a certain reserve in power anode material technology. At present, the progress of anode material technology iteration is also accelerating. Some companies' silicon carbon anodes have entered the mass production stage. The company is facing the risk of being replaced and needs to further accelerate product development. From a technical point of view, anode materials for lithium-ion batteries in the future will show diverse characteristics. Lithium battery anode material manufacturers will also expand more. The development of anode materials is high specific capacity, high charge and discharge efficiency, high cycle performance and lower cost. Various manufacturers need to strictly control the quality of their products to produce high-quality lithium battery anode materials.
