Abstract
A battery has a cathode, an anode and an electrolyte, with the cathode having a cathode current collector and a cathode material. The cathode material has a cathode active material, which is capable of reversibly intercalating and deintercalating first metal ions. The electrolyte has a solvent capable of dissolving the first metal ions and second metal ions that can be reduced to a metal during a charge cycle and be oxidized from the metal to the dissolved second metal ions during a discharge cycle. The cathode current collector has an electrochemically inert carrier and graphite. The carrier is wrapped by the graphite. The cathode current collector provided has good corrosion resistance and the battery has a long floating charge life and a low cost.
