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. Who are the manufacturers of anode materials for lithium batteries? ①Shanghai Shanshan Technology Co., Ltd. Shanghai Shanshan is a wholly-owned subsidiary of Shanshan Co., Ltd. It has five series of products including mesophase, natural graphite, artificial graphite, composite graphite, alloy and hard carbon. The current production capacity of graphite anode materials is 15,000 tons per year, and the production capacity is 35,000 tons under construction. Shanshan Technology Co., Ltd. has started a processing project of 35,000 tons of anode materials for lithium batteries in Ningbo. In the field of artificial graphite materials, it is in a leading position in the industry. At present, there is some progress in new anode projects such as silicon-carbon anode materials, soft carbon, and lithium titanate. Among them, silicon anode materials have entered the pilot stage. Since 2014, a total of 10 patent statements have been issued in the field of silicon and graphene materials, and the advantages of technology research and development have become increasingly obvious, and it has entered the PCT stage in Japan and South Korea. ②Hunan Xingcheng Graphite Technology Co., Ltd. Hunan Xingcheng Graphite is a modern enterprise invested and constructed by Dangsheng Technology, Shenzhen Innovation Investment Group, and original entrepreneur shareholders. In August 2015, Star City Graphite officially made the market in the NEEQ stock transfer system. The company's current production capacity of lithium battery anode materials is 8,000 tons, and the production capacity will reach 10,000 tons by October 2015. Its main customers include Foster, BYD, Suzhou Xingheng, CATL, etc. In the first half of 2015, the company's revenue was RMB 32,792,500, a year-on-year increase of 30%, and net profit was RMB 4.245 million, a year-on-year increase of 52%. In addition, the company has successively developed new lithium battery anode materials such as silicon carbon anode, hard carbon anode, and soft carbon anode materials. Among them, microcrystalline graphite anodes and high-performance low-cost conductive agents are already in the stage of small batch production. With capital and technological advantages, Star City Graphite's competitiveness is expected to enter the top three. ③Jiangxi Zichen Technology Co., Ltd. Zichen Technology Co., Ltd. was established in December 2012. It is a company controlled by Shanghai Putailai New Material Technology Co., Ltd. (51%). The main products are artificial graphite, composite graphite, silicon-carbon composite materials, etc. The existing production capacity is 20,000 tons. The main customers are ATL, CATL, Samsung SDI, LGC, BYD, Lishen, AVIC Lithium, and Zhuhai Coslight. In 2016, the sales revenue of anode materials for lithium batteries was about 1.052 billion yuan; the sales revenue in the first half of 2017 was about 550 million yuan. It has greater competitiveness in resource integration and capital operation. The cooperation with first-line lithium battery giants has also provided assistance for its expansion of other customers. Zichen Technology needs to accelerate its own capacity expansion to further enhance its competitiveness in the field of negative electrodes. ④Shenzhen Snow Industrial Development Co., Ltd. Shenzhen Snow Industrial Development Co., Ltd. was established in 2002. The main lithium battery products include soft carbon graphite, hard carbon graphite, graphene-carbon composite materials, silicon-carbon composite materials, lithium titanate materials, etc. In 2016, the sales revenue of anode materials was approximately 450 million yuan. Shenzhen Snow focuses on the development of artificial graphite materials. Its self-developed soft/hard carbon composite anode material has the characteristics of large rate discharge, low temperature, long cycle life and high safety. The Si-C-graphite material will be trial-produced in 2017 And supply in small quantities. ⑤Dalian Hongguang Lithium Industry Co., Ltd. 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.
