Stabilization of binder-free vanadium oxide-based oxygen electrodes using Pd clusters for Li-O 2 batteries.

A binder-free electrode 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 stability of the VO-Pd-based electrode, which can be reversibly and continuously cycled for more than 120 cycles in a Li-O-2 based battery.
