New Vanadium Phosphate Nanocomposite Li-ion Electrode Material for High-Power Batteries

By Green Car Congress on 10/02/2010 – 7:55 am PDTLeave a Comment

A team from Central South University, China; the US’s Pacific Northwest National Laboratory (PNNL); and the University of Washington have developed a new nanostructured composite vanadium phosphate material for Li-ion battery cathodes for use in high-power batteries.

The team prepared the nanostructured Li3V2(PO4)3/carbon composite by incorporating the precursor solution into a highly mesoporous carbon with an expanded pore structure.

When cycled within a voltage range of 3 to 4.3 V, the composite delivered a reversible capacity of 122 mAh g-1 at a 1C rate and maintained a specific discharge capacity of 83 mAh g-1 at a 32C rate.

These results demonstrate that cathodes made from a nano-structured Li3V2(PO4)3 and mesoporous carbon composite material have great potential for use in high-power Li-ion batteries.

A paper on their work is in press in the journal Electrochemistry Communications.
