GEM Co., Ltd.

Using nickel, cobalt, manganese and aluminium recovered from spent power batteries as feedstock, GEM industrially regenerates nickel-cobalt-manganese / nickel-cobalt-aluminium (NCM/NCA) cathode precursor materials for lithium-ion batteries, forming a closed loop of 'spent battery - precursor - cathode material'.

Covers medium-nickel, high-nickel and ultra-high-nickel core-shell concentration-gradient precursors; the official website states that these ternary precursors are used in 15% of the world's ternary-battery electric vehicles, with production capacity ranked second globally (four bases in Jingmen, Taixing, Wuxi and Fu'an with a combined 250,000 t/year).
