Abstract
This invention provides batteries with improved calendar and cycle lifetimes. A rechargeable battery comprises an additional electrode that includes active ions, such as lithium ions. Cell capacity of the battery can be increased by supplying these active ions to the anode or the cathode. In some variations, this invention provides a lithium-ion battery comprising an anode, a cathode, an electrolyte, and an additional lithium-containing electrode, wherein the additional lithium-containing electrode is capable of supplying lithium ions to the anode or the cathode in the presence of an electrical current.
