METHODS FOR DENDRITE DETECTION AND BATTERIES CONTAINING DENDRITE SENSORS

摘要

Formation of metallic dendrites within a battery can lead to catastrophic batten failure in some instances. Methods for monitoring for the presence of metallic dendrites within a battery can include measuring the electric field within the battery's separator material over a period of time. Batteries containing an electric field sensor on or in their separator material can be fabricated and their operation regulated in the event of dendrite formation. The electric field sensor is configured to detect an electric field in the separator material.
