Abstract
A method for charging an implantable medical device includes charging a lithium-ion battery provided in a medical device, the lithium-ion battery having a negative electrode with a lithium titanate active material. For at least a portion of the charging, the potential of the negative electrode is more than approximately 70 millivolts below the equilibrium potential of the negative electrode.
