Abstract: A high rate discharge battery cell 150 is disclosed. The battery cell 150 comprising an anode end 200 and a cathode end 100 contains: a laminate including at least one anode electrode sheet 102; at least one cathode electrode sheet 101; and at least one separator sheet disposed between the anode electrode sheet 102 and the cathode electrode sheet 101; wherein the anode electrode sheet 102 projects outwardly of the edge of the laminate towards the anode end 200 of the battery cell 300; the cathode electrode sheet 101 projects outwardly of the edge of the laminate towards the cathode end 100 of the battery cell 150; a first current collector 203 in electrical contact with the outwardly projecting part of the anode electrode sheet 102 in the laminate formed by metal spray; and a second current collector 103 in electrical contact with the outwardly projecting part of the cathode electrode sheet 101 in the laminate formed by metal spray.
