Abstract
In this study, the preparation of key materials and their electrochemical properties were deeply discussed. With the increasing demand for energy, traditional lithium-ion batteries have been difficult to meet the requirements of efficient energy storage, and magnesium-ion batteries have attracted much attention due to their high energy density, low cost and environmental friendliness. This study aims to develop new magnesium ion battery materials to improve their electrochemical properties. The magnesium ion cathode material was prepared by the sol-gel method and characterized with detailed physical and chemical properties. Further, we systematically evaluated the electrochemical properties of the prepared materials by using cyclic voltammetry and constant current charging and discharge tests. The results show that the material has a high specific capacity and good cycle stability, and its specific discharge specific capacity maintains a high level after several cycles. In addition, this study also innovatively explored the impact of electrolyte additives on the performance of magnesium ion batteries, and found that the appropriate amount of additives can significantly improve the cycle efficiency and discharge capacity of batteries.
