(What is the advantage and disadvantage of lithium ion battery graphite?)

Advantages of lithium ion battery graphite anode materials: (1) Graphite has a wide range of sources and abundant reserves; (2) After modification, the tap density is high; (3) The electrochemical performance is relatively stable; (4) The actual specific capacity density can be compared with the theoretical The specific capacity is close.

Disadvantages of lithium ion battery graphite anode materials: (1) Insufficient gram capacity, it is difficult to meet the actual needs of power lithium batteries; (2) low purity, more side reactions; (3) Poor stability of layered structure, after a long time It is easy to collapse after charging and discharging cycles, resulting in a serious decrease in specific capacity and a significant reduction in energy storage life; (4) The rate performance is poor, and high current charging and discharging cannot be performed, otherwise it will damage the battery; (5) The charging and discharging platform is too low.

Natural graphite and artificial graphite have always been the most widely used anode materials, but artificial graphite requires high temperature treatment in the production process, which greatly increases the production cost and adversely affects the environment.

Regarding artificial graphite, natural graphite has many advantages, such as low cost, high degree of crystallization, mature purification, pulverization, and classification technology, low charge and discharge voltage platform, and high theoretical specific capacity, which are the most important in the lithium-ion battery industry. The application lays a good foundation.

Graphite materials are considered to be the ideal anode materials for lithium-ion batteries due to their high stability, good electrical conductivity, and wide sources. However, the specific capacity and rate performance of natural graphite anode cannot meet the requirements of high-performance anode materials. In order to solve this problem, researchers have carried out a series of modification studies on it.
