摘要: The precursor synthesis of the LiNi0.8Co0.15Al0.05O2 (NCA) is usually operated in NaOH/NH3·H2O aqueous system, and pH value liquid feeding rate need strict control. Herein, a simple method was investigated without control by using urea as precipitation agent. relationship metal ions’ concentration to homogeneity studied detail. To decrease lattice disordering ratio increase reversible capacity NCA, polar CTAB molecules were added into CO(NH2)2/H2O system. NCA decreased integral electrochemical performances improved. stable battery 0.1, 0.5, 1, 2, 3, 4, 6 C can reach 188, 173, 167, 162, 152, 143, 125 mAh g−1. It expected that synthesize may provide some inspiration cathode research.
