Recent advancements in aluminum materials and aluminum electrochemistry open a current density compatibility domain in which aluminum anodes and nickel oxide cathodes can simultaneously discharge at high faradaic efficiency. The resultant overlapping comparability region permits demonstration of an aluminum/nickel battery capable of unusually high specific power density and high specific energy density: Al+3NiOOH+NaOH+3H{sub 2}O {yields} NaAl(OH){sub 4}+3Ni(OH){sub 2}. The operational cell maintains a steady-state discharge voltage in excess of 2.3 V. Aluminum/nickel battery discharges are presented which yield a power density of 915 W/kg, and a specific energy density of up to 140 Wh/kg.
