AI Technical Summary
Existing technologies cannot simultaneously and fully cover the surface of the battery, resulting in blind spots in the detection of bulging and leakage, and are not compatible with various battery shapes, making it easy to miss detections.
A flexible surface acoustic wave sensor is designed to cover the outer surface of a battery. It includes a flexible substrate and multiple integrated surface acoustic wave sensors. The sensors are arranged on the outer peripheral and end face regions, with metal interdigitators pointing inward. It adopts a multi-layer composite structure and is prepared by laser engraving and plasma treatment to achieve all-round monitoring.
It enables comprehensive monitoring of three-dimensional deformation and leakage of batteries, is applicable to batteries of various shapes, and can provide early warning of bulging and leakage risks.
