제목 Electrocatalytic Activity of Nitrogen-doped CNT Graphite Felt Hybrid for All-Vanadium Redox Flow Batteries
초록 All-vanadium redox flow batteries (VRFBs) have focused on carbon-based materials for improve their power density. VRFBs should be able to operate at high voltage during discharge at high current density.
We report a novel nitrogen-doped-CNT-containing graphite felt (N-CNT/GFs) hybrid electrodes with high electrocatalytic acitivity have been developed for the all-vanadium redox flow batteries. A simple and effective preparation method for N-CNT/GFs using metal (Fe, Co, and Ni) phthalocyanines as CNT and nitrogen precursors was presented. Higher density of N-CNTs on graphite felt gave rise to increased N-doping concentration and improved electrochemical reactivity, which results in outstanding performances in the VRFB single cell tests.
