Abstract

Abstract : A novel carbon coating method for phosphate-based VPO4 is developed via isobutanol intercalation to VOPO4 ·2H2 O combined with thermal reduction. Abstract : Here we design a novel carbon coating method for phosphate-based VPO4 with three different morphologies, via the intercalation of isobutanol to layered VOPO4 ·2H2 O combined with thermal reduction. The well-constructed flower-like VPO4 delivers a high reversible capacity of 400 mA h g −1 with a long cycle-life of more than 500 cycles, proving that the special structure is suitable to accommodate the large volume expansion during the electrochemical charge–discharge process.
