PACKAGING BAG, SECONDARY BATTERY, AND ELECTRONIC DEVICE

Abstract

This application discloses a packaging bag, a secondary battery, and an electronic device, where the packaging bag includes an encapsulation layer, a metal layer, an adhesive layer, and a packaging layer arranged in a stacked manner. The adhesive layer includes a first thermally conductive material, where a mass percentage of the first thermally conductive material in the adhesive layer is denoted as G1, and 1%≤G1≤30%. By incorporating the first thermally conductive material into the adhesive layer, heat generated during operation of the secondary battery can be more effectively conducted away, mitigating temperature rise inside the secondary battery, thereby improving the performance and safety of the secondary battery. Additionally, this enables more uniform heat distribution between the interior of the secondary battery and the packaging bag, reducing localized overheating and extending the service life of the secondary battery.
