Scaling-up the Production Process of Lithium Nickel Manganese Cobalt Oxide (NMC)

Abstract

Over the past few years, the development of lithium (Li)-ion batteries has been extensive. Several production approaches have been adopted to meet the global requirements of Li-ion battery products. In this paper, we propose a scaled-up process for the LiNi0.6Mn0.2Co0.2O2 (NMC622) cathode material for high performance Li-ion batteries. During each synthesis step, the structural and morphological characteristics of the products were comprehensively examined. The performance of the samples was evaluated directly using an 18650 full-cell-type battery. Commercial graphite and LiPF6 electrolyte were used as the anode and electrolyte, respectively. Based on the obtained data, increasing the production scale of NCM622 reduces the overall performance. Nevertheless, a simple post-treatment technique can be used to enhance the overall capacity.
