Abstract
A Li-ion and/or Li-ion polymer cell, comprised of a first cathode section and a second cathode section. Each cathode section has a cathode current collector in contact therewith. The cathode current collector is comprised of a sheet of metal mesh having a tab portion that extends outwardly from the sheet beyond the cathode section. The cathode tab from the first cathode section is disposed adjacent to the cathode tab from the second cathode section. An anode section is disposed between the cathode sections. The anode section has an anode current collector having a tab portion that extends therefrom beyond the anode section. A separator layer is disposed between the anode section and each of the cathode sections. A protective band is disposed between the tabs of each cathode current collector. The protective band is disposed between the cathode tabs and the anode section to prevent shorts when the cathode tabs are pressed together to form a single positive lead.
