Abstract
An alkaline cell comprising a housing having a bottom end and a top end, and an electrode assembly disposed within the housing. The electrode assembly comprises a single first electrode and a single second electrode, a separator therebetween, and an electrolyte. The first electrode comprises a hollow outer body and at least one inner body positioned inside the outer body, the outer body and the at least one inner body being joined together inside the housing to form a single substantially homogeneous structure having an essentially uniform electrode properties. The second electrode comprises an intermediate body at least partially disposed between the outer body and the at least one inner body and electrically isolated from the outer body and the at least one inner body.
