Abstract

Ternary materials have the characteristics of high electrochemical capacity, good cycle performance, easy synthesis, low cost, and good safety. In recent years, they have gradually replaced some lithium cobalt oxides and entered the market of cathode materials for small lithium batteries. In this paper, the α-MnO₂ precursor was prepared by hydrothermal synthesis using manganese sulfate monohydrate and sodium persulfate, and the obtained materials were then used to synthesize ternary composites by carbothermal reduction. The effects of ternary composites at different reaction temperatures and different sintering atmospheres were investigated to arrive at the optimal conditions for the preparation of the desired ternary composites. The obtained ternary composites were also subjected to physical characterization of morphology, electrical testing of impedance, cycling, and multiplier performance of lithium-ion batteries. It was found that the ternary composite samples roasted under an oxidizing atmosphere at a reaction temperature of 850 ℃ had uniform size and good dispersion, and their electrochemical properties were good.
