摘要
The fabrication process of a new, three-dimensional carbon-coated LiFePO4 electrode by sol-gel synthesis in situ on interconnected conducting fibers of carbon paper is described. This three-dimensional structure ensures overall electrode conductivity, facilitates lithium diffusion in and out of LiFePO4 particles and, hence, enables good cycling stability at 1C-rate and maximum pulse-power values that exceed those of planar LiFePO4 electrodes at high electrode loading.
