Claim 0:
1. A composite comprising:
an electrically conductive material; and
an oxide of a transition metal supported on the electrically conductive material,
wherein the transition metal is at least one of transition metals of Group 8 to Group 10 in a periodic table,
wherein the oxide of the transition metal has an amorphous structure, wherein the oxide of the transition metal is a particle having an average particle size of 100 nm or less determined from a transmission electron microscope (TEM) image,
wherein in the oxide of the transition metal, an oxidation number of the transition metal changes flexibly and reversibly in response to an applied voltage, and
wherein the oxidation number of the transition metal changes when a voltage is applied to the composite, and the oxidation number further changes when the application of voltage is released.
