Battery including beta-delithiated layered nickel oxide electrochemically active cathode material

Alkaline batteries are provided, including an anode, a cathode, and a separator disposed between the anode and cathode. The cathode porosity is selected to optimize performance characteristics of the battery. In one aspect, an alkaline cell is provided that includes (a) an anode, (b) a cathode, comprising a cathode active material, wherein the cathode has a porosity of from about 25% to about 30%, and (c) a separator disposed between the cathode and the anode.
