Abstract

The present document describes techniques for extending battery life after long-term and high-temperature storage. These techniques delay charging of a battery to detect battery conditions and determine whether the battery was exposed to high temperatures while in an idle or low-power state for a long period of time. These techniques include a methodology to relax and refresh an anode surface of the battery, after high-temperature storage, through distinct and tailored discharges prior to beginning a normal charge profile. These techniques can be applied to a wide range of chemistry platforms, which may have kinetic (Li-ion) limitations, to extend the longevity of the battery by reducing lithium plating and capacity degradation caused by long-term, high-temperature storage.
