Abstract

The LiNi0.5Mn1.5O4 cathode material has increasingly become a focal point of research. This study presents the synthesis of LiNi0.5Mn1.5O4 via a facile low-temperature coprecipitation method. The low-temperature coprecipitation method yields nano-catalytic materials with elevated specific surface areas and increased surface energy compared to conventional coprecipitation approaches. The LiNi0.5Mn1.5O4 we obtained demonstrates remarkable electrochemical properties. Specifically, the discharge capacities achieved are impressive, reaching 115.28, 101.66, and 81.51 mA h g–1 at rates of 2.0, 5.0, and 10 C, respectively. After 60 cycles, the rate is reinstated to 0.2 C, resulting in a discharge capacity of 123.96 mA h g–1, which represents a retention rate of 94.6% of the initial capacity. Our study has shown that the low-temperature coprecipitation method proves to be a practical powder technology for the production of high-performance LiNi0.5Mn1.5O4 materials.
