NMC Cathode Materials Powder
Description:
Compared with LiCoO2, which occupies the mainstream of the current market, the LiNi_xCo_ (1-x-y) layered compounds of lithium-ion battery cathode materials have MnyO_2 the advantages of high specific capacity, low cost, good stability and low pollution, and their comprehensive performance is better than any single group compound, and it is considered to be one of the most potential new cathode materials.
One of the most successful lithium ion systems is the cathode combination of nickel-manganese-Cobalt (NMC).
XIAOWEI Technology Co., Ltd. is a professional battery materials and battery equipment supplier. We can supply a full set lithium battery solution.As mentioned in the article, NMC battery cathode material is one ofthe most successful lithium ion systems, We can provide the latest NMC811 materials, NMC622, NMC532 and NMC111for your NMC lithium ion battery systems, We can also provide you other battery cathode materials, such as NCA cathode, LFP cathode, LMO material, LNMOcathode ,etc.
