Through self-developed recycling technology, CN adopts advanced separation and synthesis technology to recycle nickel, cobalt and manganese elements in spent ternary batteries. At present, we have successfully produced high-quality NCM523 ternary precursor, among which the technical indicators of nickel cobalt manganese composite hydroxide meet the industrial standards. We will continue to develop core technologies of products such as NCM622, NCM811.
