NOVELTY - The lithium-ion battery (200) comprises a positive electrode (210) comprising a first active material and a second active material, a negative electrode (220) comprising a third active material and a current collector (212), a liquid electrolyte, and a porous polymeric separator. The first active material includes lithium in the as-provided state. The second active material comprises a lithiated form of a material that does not include electrochemically cyclable lithium in the as-provided state. The second active material exhibits charging and discharging capacity.    USE - The lithium-ion battery is useful in laptop computers, cellular mobile or cordless phones, automobiles and medical devices including implantable medical devices.    ADVANTAGE - The lithium-ion battery exhibits a dramatic loss of deliverable capacity, improved performance and charge and discharge capacity, and high potential.    DETAILED DESCRIPTION - The lithium-ion battery (200) comprises a positive electrode (210) comprising a first active material and a second active material, a negative electrode (220) comprising a third active material and a current collector (212), a liquid electrolyte, and a porous polymeric separator. The first active material includes lithium in the as-provided state. The second active material comprises a lithiated form of a material that does not include electrochemically cyclable lithium in the as-provided state. The second active material exhibits charging and discharging capacity below a corrosion potential of the current collector, and comprises powdered lithium and a lithium intermetallic compound as source of electrochemically cyclable lithium. The third active material comprises a lithium titanate material. The first and second active materials are provided as separate layers. The positive and negative electrodes are provided as wound electrodes.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic cross-sectional view of a portion of a lithium-ion battery.
