Lighter weight, longer cycle life, greater capacity, longer service time, etc.
In order to solve the above problems, a new electrode material with better performance must be found, and the current commercialized lithium ion battery cathode material is mainly graphite, but the theoretical capacity of the current commercialized lithium ion battery cathode material is only 370mAh, so that the current commercialized lithium ion battery cathode material cannot meet the urgent demands of users. The cycle life of the common graphite material is about 200-300 times when the material is charged and discharged at high multiplying power. Therefore, development of batteries with faster charge speed, longer cycle life, and higher specific capacity is urgently required in the market, and development of negative electrode materials in response to such battery performance is also being pursued. As a negative electrode material of a lithium ion battery, a silicon material has been attracting attention. The theoretical capacity of the lithium ion battery is 4200mAh/g, which is more than 10 times of the commercial graphite capacity, and the lithium ion battery has the advantages of low lithium intercalation potential, low atomic weight, high energy density, low price, environmental friendliness and the like, thus being one of the optimal choices of new-generation high-capacity anode materials. However, the silicon material has poor conductivity, and the volume expansion in the charge and discharge processes is easy to cause the structural damage and mechanical crushing of the material, so that the cycle performance of the silicon material is fast attenuated, and the wider application of the silicon material is limited. In order to solve the problems, the prior art mainly comprises nano silicon particles or coating the surface of a silicon-carbon anode material, and can prevent the silicon-based material from being in direct contact with electrolyte while limiting the volume expansion of the material, so that the cycle performance of the battery is improved and side reactions between the silicon-based material and the electrolyte in the charge and discharge process are reduced. Because the graphene material has a unique flexible two-dimensional plane structure, the graphene material is an excellent coating material and can be coated on the surface of the silicon-carbon anode material. However, the bonding force between graphene sheets is generally weak, so that the coating layer formed by the graphene sheets cannot provide a large enough binding force to be used for restraining the volume expansion of the silicon-carbon anode material in the charge-discharge process, thereby influencing the electrochemical performance of the silicon-carbon anode material.
