AI Technical Summary
Technical Problem
The occurrence of internal short circuits in power storage devices, particularly secondary batteries, is a significant challenge that existing technologies have not adequately addressed.
Method used
The energy storage device incorporates a separator that constitutes the outer surface of the electrode body and is bonded to a spacer, which is positioned between the case and the electrode body, thereby preventing the separator from peeling off and reducing the risk of internal short circuits.
Benefits of technology
This configuration effectively suppresses the occurrence of internal short circuits by maintaining the integrity of the separator, preventing exposure of electrodes and foreign matter ingress, thus enhancing the safety and reliability of the energy storage device.
