Research on the Positive Electrode Performance of Lithium Battery Based on the Mixture of Carbon Fluoride and Manganese Dioxide

In this paper, α-manganese dioxide (MnO2) with good electrical conductivity was selected as the cathode material of lithium batteries. Fluorocarbon/MnO2 composites were prepared by the solid-phase method. The phase structure, microstructure, and electrochemical properties of the composites were characterized and analyzed. Manganese dioxide is one of the most widely used cathode materials in primary lithium batteries. It has the characteristics of low cost, good ion exchange, and molecular adsorption properties and excellent electrochemical properties. The purpose of this study was to further explore the effects of different manganese dioxide content composites on the electrochemical performance of lithium batteries.
