    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 Substrate Dissolution Potential (SDP) to thus avoid low voltage substrate damage.
