1. A battery comprising:
- a positive electrode comprising a current collector and a first active material; and
a negative electrode comprising a current collector, a second active material, and a third active material;
wherein the first active material, second active material, and third active material are configured to allow doping and undoping of lithium ions; and
wherein 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.
