要約(英語): In this study, high voltage is applied to the spherical electrode (diameter: 100mm), and the influence of the high electric field on the lithium ion battery (LIB) is verified. (1) Provide an air gap (20mm) only on the positive electrode of the LIB, and ground the negative electrode. When +10kV is applied, it is charged 15.8mV, and when -10kV is applied, it is discharged 10.7mV. The influence of deterioration on the LIB due to the high electric field was not observed. In addition, provide an air gap (10mm) on the both electrodes of the LIB. In both cases of ±10kV, the voltage of the LIB was charged and discharged by about 5mV. (2) When an air gap (20mm) was provided only on the positive electrode side of the LIB and a 10kVpp sine wave was applied at 50Hz, the LIB was slightly charged. (3) Provide an air gap (20mm) only on the positive electrode side of the LIB, and then apply +10kV (120h). As a result, the LIB was overcharged and the discharge capacity was greatly degraded. However, it is thought that there is almost no impact on the LIB if it is about several hours.
