Title: Microwave-assisted preparation of Li{sub 3}V{sub 2}(PO{sub 4}){sub 3}/C composite with high-rate capacity

Abstract

Highlights: ► High-rate Li{sub 3}V{sub 2}(PO{sub 4}){sub 3}/C is firstly reported via a microwave-assisted method. ► The reduced particle size is responsible for the improved high-rate performance. ► A discharge capacity of 100 mAh g{sup −1} is obtained at 20 C charge–discharge rate. -- Abstract: A fast sol–gel assisted microwave heating approach has been developed for the synthesis of high-rate Li{sub 3}V{sub 2}(PO{sub 4}){sub 3}/C cathode material. This approach can synthesize Li{sub 3}V{sub 2}(PO{sub 4}){sub 3}/C particles with high purity and good crystallinity in 12 min at a low microwave power of 320 W. In the voltage range of 3.0–4.3 V, the obtained Li{sub 3}V{sub 2}(PO{sub 4}){sub 3}/C delivers a reversible discharge capacity of 100 mAh g{sup −1} after 100 cycles at 20 °C, exhibiting excellent rate capability and cycling performance. The rate-recovery performance also suggests that the Li{sub 3}V{sub 2}(PO{sub 4}){sub 3}/C material possesses excellent structure stability after high-rate cycles, presenting excellent application value in high-power lithium ion batteries.
