Products Description
Lithium nickel-cobalt-manganate(NCM) is a key ternary cathode material for lithium-ion batteries, and its chemical formula is LiNixCoyMn1-x-yO2. Has a higher specific capacity and lower cost than the unit cathode material. Lithium cobaltate is one of the most widely used battery materials, but cobalt resources are increasingly scarce, the price is expensive, and there are security risks in the use of lithium cobaltate batteries.
Lithium nickel-cobalt manganate replaces more than two-thirds of cobalt in lithium cobaltate with relatively cheap nickel and manganese, and the cost advantage is very obvious. Compared with other lithium ion battery cathode materials lithium manganate and lithium ferrous phosphate, lithium nickel-cobalt manganate and lithium cobaltate are very close in terms of electrochemical performance and processing performance, making lithium nickel-cobalt manganate material become a new battery material and gradually replace lithium cobaltate. Become the darling of a new generation of lithium-ion battery materials.
Xiaowei can provide the latest NMC811 materials, NMC622, NMC532 and NMC111 for 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.
