Abstract
Abstract LiVPO4F/C cathode material was synthesized by a novel one-step solid-state reaction method using humic acid as both reduction agent and carbon sources. The SEM image showed that the particles merged with each other to form a porous structure. Electrochemical test showed that the initial discharge capacity of LiVPO4F/C powder was 139 mA h g−1 and the capacity was 132 mA h g−1 after 30 cycles.
