The silicon carbon negative electrode coating equipment introduces to you that silicon carbon negative electrode materials are a type of material that doping silicon materials with carbon materials of different structures to improve the capacity and electrochemical performance of negative electrode materials
At present, silicon is a known material that can be used for the theoretical specific capacity of negative electrode materials, which can reach 10 times the mainstream graphite negative electrode. It has the advantages of good safety, abundant resource reserves, and low production costs. Carbon materials have relatively high conductivity, relatively stable structure, and small volume expansion during cycling, usually below 10%. They also have good flexibility and lubricity Silicon negative electrode materials have problems such as low cycling life, significant volume changes, and sustained generation of SEI films, but silicon carbon negative electrode materials can improve these problems. The silicon carbon negative electrode coating equipment introduces to you the advantages of silicon carbon negative electrode materials, which combine the above two and are the focus of future development of negative electrode materials The silicon carbon negative electrode coating equipment introduces to you that the theoretical lithium storage capacity of silicon carbon negative electrode materials can reach 4200mAh/g, which is almost 10 times more than the 372mAh/g of graphite negative electrode materials currently widely used
