Stabilization of binder-free vanadium oxide-based oxygen electrode using Pd clusters for Li-O2 battery

A binder-free electrde consisting of Pd clusters and vanadium oxide (VO) has been prepared via gas-phase-cluster beam deposition on carbon cloth. The Pd clusters largely improve the stablity of the VO-Pd-based electrode, which can be reversibly and continuously cycled for more than 120 cycles in a Li-O2 based battery.
