Abstract
Disclosed is a battery comprising a cathode, an anode and an electrolyte; the cathode comprises a cathode material, the cathode material comprises a cathode active material which is capable of reversibly intercalating and deintercalating a first metal ions; the electrolyte comprises at least a solvent capable of dissolving solute, the solute being ionized to a second metal ions that can be reduced to a metallic state during a charge cycle and be oxidized from the metallic state to the second metal ions during a discharge cycle and the first metal ions that can deintercalate from the cathode active material during the charge cycle and intercalate into the cathode active material during the discharge cycle; and the anode and/or the electrolyte further comprise an additive which is a bismuth compound. The gas production amount could be effectively reduced when the battery is being used.
