Abstract
According to the current performance improvement demand of lithium-ion battery, this study explores the synthesis method of new lithium-ion battery materials, and studies its performance in depth. By using the advanced sol-gel method, a new type of lithium-ion battery cathode material was successfully synthesized. The material maintains the advantages of traditional lithium-ion battery materials while significantly improving the energy density and cycle stability. In the experiments, we examined the structural characteristics, electrochemical properties and charge-discharge cycle stability of the material in detail. The results show that the new materials show excellent performance in the charge and discharging process, and their initial discharge capacity and cycle efficiency are significantly higher than those of the conventional materials. Moreover, this study innovatively explored the relationship between the synthesis conditions of materials and their electrochemical properties, which provides a theoretical basis for further optimization of material properties.
