[ABSTRACT ]

Nickel, one of the metals in the spent catalyst, currently experiencing an increase in demand as a raw material for lithium-ion battery cathodes. Therefore, this study used nickel from the spent catalyst to produce Lithium Nickel Manganese Cobalt Oxide (NMC) material with various ratios of Ni: Mn: Co = 1: 1: 1, 4: 2: 2, and 5: 3: 2. The results showed that precursors and products for the three types of NMCs had a highly ordered hexagonal structure and high crystallinity. Furthermore, electrochemical performance tests at 0.1C showed specific discharge capacities of 93.989 mAh/g, 63.346 mAh/g, and 84.202 mAh/g for NMC111, NMC442, and NMC532, respectively.
