Description

technical field

[0001] The invention relates to a preparation method of a lithium-iron disulfide battery cathode material, belonging to the technical field of new materials. Background technique

[0002] Lithium-iron disulfide battery is a high-energy, light-weight, and environmentally friendly primary lithium battery with a working voltage of 1.5V. It can be used interchangeably with alkaline-manganese batteries, nickel-metal hydride, nickel-cadmium, and zinc-silver batteries. Its discharge platform is stable and its storage life is long. , Excellent safety performance. The theoretical capacity of iron disulfide, the positive electrode material of the battery, is 890mAh / g, and the capacity of a single AA (No. 5) battery is higher than 3000mAh. Especially when used in heavy load applications, its performance is 4 to 10 times that of ordinary batteries. At present, it is mainly used in electrical appliances such as digital cameras, MP3, PDAs, handheld game consoles, portable...
