Abstract In this paper, a novel composite as cathode material for lithium-ion batteries is preparaed by using a sol-gel and carbon thermal reduction me-thod to combine a good electrical conductive porous carbon with lithium vanadium phosphate. The new cathode has an initial specific capacity of 111.0 mA·h·g-1, and a capacity retention rate of 99.2% after 150 cycles at a rate of 0.5C. The composite cathode still has a specific capacity of 79.8 mA·h·g-1 and a capacity retention of 71.9% at 10C, showing a good fast charge/discharge performance. The simple preparation process, excellent electrochemical performance and high LVP content satisfies the requirements of the industrial applications for cathode materials on lithium-ion battery, and the composite is a effective material for the industrialization of the fast charge battery.
