Patent ID: 8153308

Claim:
An electrode, comprising: an electrically conductive substrate; and a material capable of storing hydrogen on a surface thereof supported by the substrate, wherein the hydrogen storage material is formed by contacting a powder composition with a first solution prior to electrode fabrication and by contacting the hydrogen storage material to a second solution subsequent to electrode fabrication and wherein the hydrogen storage material comprises one or more of MmNi 4.65 Co 0.88 Mn 0.45 Al 0.05 ; MmNi 3.55 Mn 0.4 Al 0.3 Co 0.4 Fe 0.35 ; V 2.1 TiNi 0.5 Hf 0.05 Co x (x=0 to 0.192); LaNi 3.55 Mn 0.4 Al 0.3 (Co 1-x Fe x ) 0.75 (0<x<1); La 2 Mg(Ni 1-x Al x ) 9 (x=0 to 0.05); Zr 1-x Ti x Cr 0.4 Mn 0.2 V 0.1 Ni 1.3 (x<1); Zr(Fe 0.8 Cu 0.2 ) 2 ; Zr(Fe 0.8 Cu 0.1 Co 0.1 ) 2 ; Mg 67-x Ca x Ni 33 ; Mg—TiFe 0.92 Mn 0.08 ; Mg 87 Ni 10 Al 3 ; Ti 0.4 Zr 0.6 Cr 0.85 Fe 0.7 Ni 0.2 Mn 0.25 Cu 0.03 ; or metal-benzenedicarboxylate M(OH)(O 2 C—C 6 H 4 —CO 2 ) (M=Al, Cr); and the first solution comprises a first reducing agent and a first alkaline base, and the second solution comprises a second reducing agent and a second alkaline base.
