Carbon-coated V2O5 nanoparticles were synthesized by a facile synthetic process using as-synthesized MIL-47(V) (MIL-47(V) as) as both vanadium and carbon precursors with controlled heat treatment. The synthesized V2O5 nanoparticles had a thin (4-6 nm) carbon-coating layer, formed by the controlled thermal decomposition of the carboxylate groups of MIL-47(V) as. The highly crystallized and carbon-coated V2O5 nanoparticles exhibited an enhanced initial discharge capacity of similar to 286 mA h g(-1) and good capacity retention of similar to 91%, after 50 cycles at a rate of 0.1 C, for voltages in the 2.1-4.0 V range.
