1. A lithium-ion battery comprising:
- a positive electrode comprisinga positive current collector,a first active material, anda second active material; and
a negative electrode comprisinga negative current collector,a third active material, anda quantity of lithium in electrical contact with the negative current collector;
wherein the first active material, second active material, and third active materials are configured to allow doping and undoping of lithium ions; and
wherein the quantity of lithium provides electrochemically cyclable lithium for the second active material of the positive electrode to allow the second active material to exhibit charging and discharging capacity below a corrosion potential of the negative current collector and above a decomposition potential of the first active material.
