Abstract
A rechargeable battery cell includes an anode with a major portion of active material, a cathode including MnO.sub.2 doped with bismuth, and a separator between the cathode and anode which substantially prevents bismuth from migrating from the cathode to the anode. The rechargeable battery cell has a high cycle life and does not contain toxic compounds found in conventional rechargeable batteries.
