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 [Formula: see text][Formula: see text][Formula: see text][Formula: see text]O2 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. [Formula: see text][Formula: see text][Formula: see text][Formula: see text]O2 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.
