A medical device includes a rechargeable lithium-ion battery for providing power to the medical device. The lithium-ion battery includes a positive electrode including a current collector, a first active material, and a second active material. The lithium-ion battery also includes a negative electrode including a current collector, a third active material, and a quantity of lithium in electrical contact with the current collector of the negative electrode. The second 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.
