説明
In order to detect degradation and damage in lithium ion batteries, the acoustic emission (AE) technique was applied. The AE signals generated in the battery during the charge - discharge cycles were monitored at three different charging and discharging rates. Highly oriented pyrolytic graphite (HOPG) and lithium metal were used as working and counter electrodes, respectively. AE signals were mainly detected during the first charge and the AE event rate increased near the potential plateau that appears during changing a phase of the graphite depending on the degree of intercalation of the lithium. Source of these signals were assumed to be the formation of solid electrolyte interface (SEI) on the graphite surface. AE signals from the graphite fracture were also mainly detected during charging. However, when a short in the battery occurred, AE signals induced by the fracture were detected even during discharging. The charge - discharge cycle tests were next studied. The AE generation rate decreased as the cycle number increased. Its tendency did not depend on the charging rate. The AE generation rate increased just before a short circuit in the battery occurred.
