ABSTRACT:
An electrochemical battery cell in accordance with the invention has a high electrode interfacial surface area to improve high rate discharge capacity, and the shapes of the electrodes facilitate the manufacture of cells of high quality and reliability at high speeds suitable for large scale production. The interfacial surfaces of the solid body electrodes have radially extending lobes that increase the interfacial surface area. The lobes do not have sharp corners, and the concave areas formed between the lobes are wide open, to facilitate assembly of the separator and insertion of the other electrode into the concave areas without leaving voids between the separator and either electrode.
