Hunan Yuneng publicly disclosed an invention patent titled "A High C-Rate Cycling Performance LFP Cathode Material" on December 31, 2024, with the publication number CN119230806A and the application date of December 5, 2024. This technology employs the sol-gel method to prepare LFP cathode material, utilizing the synergistic effects among chitosan, citric acid, and graphene oxide to ensure uniform, complete, and dense coating of the material. This structural design effectively provides continuous electron migration pathways, significantly reducing the impedance of the cathode material during high C-rate cycling, thereby enhancing its electrochemical performance.
