Abstract
A battery includes a housing and a laminate in the housing. The laminate includes an anode and cathode, each having a first end and an opposing second end. The anode includes an anode collector including a first sheet of patterned conductive material having a first active area and a first plurality of conductive tabs formed integrally with the first active area, and a first active material on the first active area of the anode collector. The cathode includes a cathode collector including a second sheet of patterned conductive material having a second active area and a second plurality of conductive tabs formed integrally with the second active area, and a second active material on the second active area of the cathode collector. Active material is not on either the first or second plurality of conductive tabs. A separator is positioned between the anode and the cathode.
