▎ 摘 要
NOVELTY - Rapidly synthesizing sodium vanadium fluorophosphate anode material comprises (i) taking 3 mol pts. wt. sodium fluoride and 2 mol pts. wt. vanadium phosphate, adding 1-10% carbon source, adding 0.1-1 mol pts. wt. fluorine source to make up the loss of fluorine element, mechanically activating for 0.5-24 hours, mixing the raw materials uniformly, and (ii) placing the obtained precursor on the carrier in the inert atmosphere, connecting the carrier with the direct current power supply, where the electrifying current is 8-45 A, and the duration is 5-35 seconds to obtain sodium vanadium fluorophosphate anode material. USE - The method is useful for quickly synthesizing sodium vanadium fluorophosphate anode material. ADVANTAGE - The method enables to synthesize sodium vanadium fluorophosphate anode material that has good crystallinity, less impurity and small crystal grain size; has short heating time, less fluorine element loss, better capacity and cycle performance than the tube furnace sintering and has reduced energy consumption.
