Abstract
A lithium ion battery particularly configured to be able to discharge to a very low voltage, e.g. zero volts, without causing permanent damage to the battery. More particularly, the battery is configured to define a Zero Volt Crossing Potential (ZCP) which is lower than a Damage Potential Threshold (DPT). A method for using a battery capable of tolerating discharge to zero volts is also disclosed.
