Oxalate co-precipitation synthesis of LiNi0.45Cr0.05Mn1.5O4/Ag composite for lithium-ion batteries
The rate capability and cyclic performance of the LiNi0.5Mn1.5O4 under high current density have been significantly improved by doping a small amount of chromium (Cr). Specifically, LiNi0.45Cr0.05Mn1.5O4 and LiNi0.45Cr0.05Mn1.5O4/Ag synthesized by co-precipitation reaction can respectively deliver a discharge capacity of 122 and 128 mA h g–1 at 5 °C rate. At 0.5 C discharge rate, LiNi0.45Cr0.05Mn1.5O4 and LiNi0.45Cr0.05Mn1.5O4/Ag can maintain 94.6% and 98.5% of their initial capacity after 200 cycles respectively. The result demonstrates that Cr-doping and Ag-coating could be a way to enhance the electrochemical performance of spinel LiNi0.5Mn1.5O4.
