Multifunctional transition metal oxides or phosphorous oxides are described where two transition metals are included in the structure. The first transition metal forms a layered structure as an oxide or phosphorous oxide. The second transition metal is located between the layers of the structure as a reducible cation. Specific examples of two material families will be introduced including silver vanadium oxide, AgxVyOz, and silver vanadium phosphorous oxide, AgwVxPyOz. The silver cation is electrochemically reduced to form a conductive silver metal network through reduction of Ag+ to Ag0. The vanadium centers are reduced from vanadium +5 to +4 and +3 providing multiple electron transfer per formula unit. Detailed characterization and electrochemistry are included.
