Lithium ion Battery Cathode Raw Materials LiNiMnCoO2 NCM811 NMC811 Black Powder for Lab
NMC 811 is a black powder for lithium ion battery cathode raw material. Full chemical format is LiNiMnCoO2, NMC 811 means that Nickel:Manganese:Cobalt=1:1:1.
The lithium nickel cobalt manganese battery is safer than lithium cobalt oxide battery. The finished lithium battery mainly used forcompact electrictool or equipment. High nickel type NMC material has larger capacity of battery.
