제목 C-Na3V1.96Fe0.04(PO4)3/Fe2P Nanoclusters As Cathode Materials for High-Pwoer Sodium-Ion Batteries
초록 In this presentation, I synthesied the carbon-coated Na3V1.96Fe0.04(PO4)3-Fe2P composite (NVFP-FP/C) through a one-pot pyro-synthesis method and propoed as potential cathode for high-rate sodium-ion batteries. The Na3V1.96Fe0.04(PO4)3-Fe2P composite consists of unique nanoclusters of electrically conductive ultra-fine Fe2P crystals randomly dispersed among the NVP particles. The presence of Fe2P in the composite cathode greatly enhances its electronic conductivity and Na+-ion diffusion co-efficient; hence, the NVFP-FP/C cathode exhibits a high discharge capacity, remarkable long term cycling stability over 2000 cycles at 20 C and excellent power capability up to 40 C.
