US 12,609,418 B2 · Metal can battery with stepped enclosure

Abstract

Can battery cells are described. The can battery cell includes a battery cell core that is housed in a rigid enclosure. The enclosure can be made of metal or other rigid material. A front face of the enclosure includes an anode tab and a cathode tab extending from the front face. A circuit module is electrically coupled to the anode tab and the cathode tab, and overlies at least a portion of the front face of the enclosure. One of the anode tab or the cathode tab is electrically coupled to the battery enclosure. The other of the anode tab or the cathode tab is electrically insulated from the enclosure. The front face includes a protrusion portion that forms a step-like structure in the front face of the enclosure.
