Lithium nickel cobalt manganese oxide exhibits low impedance growth. The products are produced using a suitable continuous precursor, optimized Li/Me ratio, a special doping process, and special processing techniques with advanced equipment. By being properly proportioned, the product achieves high capacity, low initial resistance, good cycling performance, and low impedance growth during cycling.
