Teach the advantages and disadvantages of graphite anode materials for lithium-ion batteries

Benefits of graphite anode materials for lithium-ion batteries: (1) Graphite is widely used and has rich reserves; (2) The tap density after modification is higher; (3) The electrochemical performance is relatively unchanged; (4) The actual specific capacity density It can be close to the theoretical specific capacity. Disadvantages of graphite anode materials for lithium-ion batteries: (1) The gram capacity is insufficient, which makes it difficult to meet the actual needs of power lithium batteries; (2) The purity is low, and the side effects are more; It is easy to collapse after a long period of charging and discharging cycles, resulting in a serious decrease in specific capacity and a drastically shortened energy storage life; (4) The rate function is poor, and high current charging and discharging cannot be performed, will it damage the battery; (5) The charging and discharging platform is too high low. Natural graphite and artificial graphite have always been the most widely used negative electrode materials, but artificial graphite has to be processed at high temperatures during the production process, which greatly increases its production cost and presents an unlucky influence on the situation. Regarding artificial graphite, natural graphite has many benefits. It has low cost, high crystallization level, mature purification, destruction, and grading skills, low charge and discharge voltage platform, and high theoretical specific capacity. These are its advantages in the lithium-ion battery industry. The application laid the foundation for a brilliant foundation. Graphite materials are considered to be the most ambitious negative materials for lithium-ion batteries due to their high invariance, good conductivity, and wide-ranging origins. However, the specific capacity and rate performance of natural graphite anodes cannot satisfy the requirements of high-performance anode materials. To solve this problem, researchers have conducted a series of modification studies on it. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
