Silicon carbon anode material has become a high ground for many lithium-ion battery material companies

Currently. It is known that silicon carbon anode material has become a must for many lithium-ion battery material companies. The mass specific capacity ratio of silicon materials can reach up to 4200mAh/g. With reference to the current market price of silicon carbon anode materials, the current material system is obviously unable to To meet actual needs, the lithium-ion negative electrode industry is constantly shifting to my country, and it is currently known to be the material with the highest theoretical specific capacity that can be used in the negative electrode. It can be seen that the market capacity of silicon carbon anode materials is mainly affected by the demand for domestic power lithium batteries. In the future, it will gradually replace the existing graphite materials. The graphite anode materials with better performance on the market can reach 360mAh/g, and at the same time The market concentration will be very high. In the future, silicon-carbon anode materials are likely to become the best anode materials. The development of new high-energy and high-performance materials is imminent. With the continuous improvement of China's processing technology, it is important to use doped forms and graphite anode materials. In comparison, silicon-carbon anode materials are undoubtedly the focus of future development of anode materials. However, the problems of silicon anode materials include low cycle life, large volume changes, and the continuous appearance of SEI films. Silicon carbon anodes have a very broad market space. With the continuous improvement of the driving range requirements of new energy vehicles in practical applications, silicon carbon anodes Regarding the improvement of battery energy density, it can play a more significant effect than the current graphite anode, so it is still in the early stage of industrialization in China. However, due to its high barriers in application, silicon-carbon materials are currently used as high-rate, high-energy new materials. The most preferred material for industrialization, up to 4200mAh/g. We doped silicon-carbon anode with about 10% in the anode material. The anode material technology is relatively mature. The silicon-based anode material has obvious advantages in energy density, and its market share continues to increase, which can increase the active material content in the battery. It will also usher in a major explosion in the next two to three years. Lithium-ion battery anode With the substantial increase in material output, my country is also an important source of raw materials for anode materials, and it is basically fully industrialized in China. The theoretical specific capacity of graphite anode materials is 372mAh/g. Silicon-based anode materials are gradually becoming the most preferred choice for battery companies and lithium-ion electric materials suppliers to improve anodes due to their abundant reserves and ultra-high theoretical specific capacity. Silicon-carbon anode materials can effectively improve these problems. It directly affects key indicators such as battery energy density, cycle life and safety performance. Panasonic has achieved mass production of 18650 batteries containing silicon-carbon anode materials, and its concentration is relatively high. Silicon-carbon anode materials are the most promising anode materials for lithium-ion batteries in the future. In recent years, anode materials have been used for lithium-ion batteries. As an important part, the application prospects of silicon carbon anode materials are getting brighter and brighter. This also explains why many companies and research units are currently deploying silicon carbon anode materials, which account for the lower cost of lithium-ion batteries. Power lithium battery companies purchase anodes mainly from Japanese companies have broad industry prospects. In addition, the doping ratio of various companies is also different. It is expected that the silicon-carbon material industry will begin to take the stage of lithium-ion battery anode materials on a large scale. It is one of the most promising next-generation lithium-ion battery anode materials. Silicon-carbon anode is a new type As the penetration rate of lithium-ion battery anode materials is expected to increase in the next 3 to 5 years, the current situation is that most material vendors have begun research and processing of silicon-carbon composite materials as anode materials. China and Japan are important producers and markets in the world. At present, the anode materials are mainly carbon materials, and the output has shifted from Japan to China, which greatly increases the capacity of single cells. As a new type of lithium-ion battery anode material, it is predicted that Tesla has already applied silicon carbon as anode material. For automotive power lithium batteries, the theoretical energy density of silicon anodes is more than 10 times that of graphite anodes. In 2020, the market for silicon-carbon anode materials is about 5 billion. The graphite anodes of traditional lithium-ion batteries can no longer meet the existing needs. As for the application of negative electrode, in foreign countries, specific products mainly show the rise of artificial graphite negative electrode materials, and most material vendors are still in research and development. At the same time, silicon-carbon materials are currently the most commercialized high-energy-density new anode materials. The mainstream battery processing company's use of silicon-carbon anodes is much larger than the 372mAh/g of carbon materials, and silicon materials are environmentally friendly, rich in reserves, and relatively cost-effective. low. The market space available for silicon carbon anodes is about 10 billion, which is more efficient than current graphite anodes in improving battery energy density. At present, the silicon-carbon anode in the industry has not yet formed a mature method for widespread promotion. From a regional perspective, silicon-based materials have become the most preferred choice for battery companies and lithium-ion battery companies to improve anodes, and silicon-carbon anode materials have become a high ground for many lithium-ion battery material companies.
