One-Pot Combustion Synthesis of Lithium Nickel Cobalt Aluminium Oxide Cathode Material for Lithium-Ion Battery

Abstract

The synthesis of Ni0.8Co0.15Al0.05O2 (NCA) cathode material is performed using the one-pot synthesis. This system is combined with the solution combustion method to produce ternary metal oxide (TMO). Nitric acid acts as an oxidizer and various amount of urea act as fuel for the combustion process. NCA material has a good hexagonal layer structure and the average particle size obtained was 1.17 µm. The electrochemical analysis showed that NCA cathode material obtained at a ratio NCA-OH: urea = 1: 2 has the highest specific discharge capacities of 118.617 mAh.g-1, with a stability of up to 10 cycles.
