Enhanced Electrochemical Performance of LiNi1/3Co1/3Mn1/3O2 at a High Cut-Off Voltage of 4.6 V by Li1.3Al0.3Ti1.7(PO4)3 Coating

At present, LiNi1/3Co1/3Mn1/3O2 (NCM) is a widely used material in the commercial market due to easy control of preparation process and usage environment. However, its capacity keeps fading when cut-off voltage increases. In this research, an Li1.3Al0.3Ti1.7(PO4)3 (LATP) coating method proposed improve cycle performance at high 4.6 V. The battery prepared with LATP-modified NCM exhibits increased discharge retention 92.37% after 100 cycles 0.2C (1C = 200 mA g−1), while bare only presents 64.28%. Our results indicate that LATP-surface might be useful increase stability other high-capacity cathode materials.
