The industrial production of lithium-sulfur batteries has become a problem, and the core problem of lithium-sulfur batteries lies in the positive electrode materials. This paper is mainly to improve the cathode material of lithium-sulfur batteries. In order to improve the conductivity of the positive electrode of sulfur, to solve the volume expansion of sulfur during discharge, to inhibit the dissolution of polysulfide in the electrolyte and the shuttle effect, this paper improved the high electrochemical performance of lithium-sulfur batteries and promoted the industrialization of lithium-sulfur batteries. Simultaneously, combined with wavelet analysis and transform image processing technology, this paper conducted qualitative analysis on the performance of battery materials, and combined experiments to conduct research and analysis. Experiments show that the method proposed in this study is scientific and can provide theoretical reference for subsequent related research.
