Description

technical field

[0001] The invention relates to a preparation method of carbon fluoride material, which belongs to the field of preparation of lithium battery materials. Background technique

[0002] At present, the energy density of commercial lithium-ion batteries is low, and it is difficult to meet the requirements of high-energy-density power supplies for electrical equipment, especially the power supply for high-intensity individual combat systems. Therefore, the development of lithium batteries with ultra-high energy density, good stability and reliability has become an urgent research task.

[0003] Lithium-carbon fluoride batteries have the advantages of ultra-high theoretical specific capacity, high stable discharge voltage, and low discharge rate, and are the first lithium primary batteries to be commercialized. In the military field, lithium-carbon fluoride batteries also have special applications, such as electric shock and fuze grenades. If ordinary batteries a...
