Abstract:
A battery includes a positive electrode having a current collector and a first active material and a negative electrode having a current collector and a second active material. The battery also includes an auxiliary electrode having a current collector and a third active material. The auxiliary electrode is configured for selective electrical connection to one of the positive electrode and the negative electrode. The first active material, second active material, and third active material are configured to allow doping and undoping of lithium ions. The third active material exhibits charging and discharging capacity below a corrosion potential of the current collector of the negative electrode and above a decomposition potential of the first active material.
