Water-Cooked Cu[sub 2]O Films for Lithium-Ion Batteries

Abstract
Cu2OCu2O films were directly synthesized by cooking copper plates in saturated CuSO4CuSO4 solution. The resulting films exhibited interesting lithium storage capability as anodes of lithium-ion batteries. Desirable electrochemical performance was achieved after the Cu2OCu2O films were further coated with Ni particles via electroless plating. The factor that influenced the electrochemical performance of the films was investigated as well. The present finding provides an alternative method to fabricate transition metal oxide films for potential power source applications.
