Highly ordered spherical LiFePO4 is synthesized by an intermittent microwave heating assisted water-bath reaction and the resulted LiFePO4 shows high tap-density of 2.0 g cm-3 and volumetric specific capacity of 325 mAh cm-3 when used as cathode material in Li-ion battery. The high performance of the ordered spherical LiFePO4 is explained in terms of the high conductivity and the improved mass transfer kinetics. Such highly ordered spherical LiFePO4 with improved volumetric specific capacity will be potentially used in the high-power Li-ion batteries for electric vehicles.

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.
