Solution Overview

Ternary materials usually refer to nickel cobalt manganese oxide lithium（NCM） or nickel cobalt aluminum oxide lithium（NCA）, which are important categories of cathode materials for lithium batteries. With high energy density as the core advantage, they are widely used in EV(especially high-end models), consumer electronics and other fields. Its production line needs to be controlled through refined processes to convert various metal raw materials into composite oxide powders that meet battery performance requirements.
