What are the cathode materials of CR2025 battery?

　　Lithium battery cathode materials include lithium cobalt metal oxide, lithium nickel metal oxide, lithium manganese metal oxide and polyanion battery cathode materials.

　　1.Lithium cobalt oxide

　　Lithium cobalt oxide is the most successful and commonly used cathode material in commercial lithium-ion batteries. It has good effects in terms of crossover, charge and discharge capacity, high battery charging efficiency, and stable working voltage.

　　2. Lithium nickel oxide

　　Lithium nickelate (linio2) is a cubic rock salt structure, the same as licoo2, but the price is lower than licoo2. The basic theoretical volume of Linio2 is 276mah/g, the specific volume is 140180mah/g, the working standard voltage category is 66, and it is not subject to charging restrictions. It has the characteristics of high-temperature reliability, low lithium-ion battery life and zero pollution. As the cathode material of lithium-ion batteries, Linio2 has the following problems that require scientific research and treatment.

　　3.Lithium manganese oxide

　　In my country, manganese resources are abundant, manganese is non-toxic and has little environmental pollution. Therefore, the plate interface 2 and the spinel interface 2O4 have become a hot topic in cathode material research.

　　4. Manganese nickel cobalt composite oxide

　　Licoo2, Linio2 and Limno2 were synthesized using the positive materials of layered Mn-Ni-Co composite metal oxide batteries. This composite material is better than the positive materials of any single-component battery and has significant ternary interactions. Introducing Co can reduce positive ions, reduce space-occupying damage, and stabilize the layer structure of raw materials. The introduction of Ni can increase the volume of raw materials, reduce the cost of raw materials, and improve the safety factor of raw materials. The limnxniyco1-x-yo2 battery charging service platform is slightly higher than licoo2 and is suitable for various CR2025 battery.

　　5.Lithium vanadium oxide

　　Vanadium is a multivalent metal material, and lithium can produce a variety of metal oxides, including layered Livo2, Lixv2O4, Li1xv3O8, spinel-type Liv2O4, and spinel-type Livmo4 (mNi, co).
