Medical device having lithium-ion battery
First Claim
1. A medical device comprising:
- a rechargeable lithium-ion battery for providing power to the medical device, the lithium-ion battery comprising;
a positive electrode comprising a current collector, a first active material, and a second active material; and
a negative electrode comprising a current collector, a third active material, and a quantity of lithium in electrical contact with the current collector of the negative electrode;
wherein 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;
whereby the rechargeable lithium-ion battery may be discharged completely without a substantial reduction in battery capacity during subsequent charge cycling of the battery.
