Synthesis of Li1.2Mn0.54Ni0.13Co0.13O2 Nanorods by a Facile Self-Template Method and their Electrochemical Performances
Abstract
Lithium-rich manganese-based oxides have become one of the widely studied cathode materials for lithium-ion batteries due to their high-energy density, relatively low price and environmental friendliness. Herein, we propose a simple self-template route to prepare Li1.2Mn0.54Ni0.13Co0.13O2 nanorods using rod-like Mn2O3 as templates. Besides, the effect of calcination temperature on the morphology and electrochemical properties of the electrode materials was investigated. Li1.2Mn0.54Ni0.13Co0.13O2 nanorods as the cathode exhibit initial capacity of 251.4 mAh gt1 at 0.1 C and capacity retention rate of 67.9% after 200 cycles, which can be attributed to the enhanced layered structural stability, lower charge transfer resistance and shorter lithium-ion transport pathway.
