Abstract

The present disclosure provides a soft package battery and an electric device, the soft package battery comprises a battery body and a protection plate, the battery body comprises an encapsulation body and an electrode core, the encapsulation body only comprises a main body part and an end part; the protection plate comprises a first surface and a second surface, the second surface is closer to the end surface of the main body part than the first surface, the first surface is farther away from the end surface of the main body part than the bending segment, the shortest distance between the first surface and the bending segment is D1, the shortest distance between the second surface and the end surface of the main body part is D2, 0.05mm≤D1≤1mm, 0.05mm≤D2≤0.5mm. Compared with the related art, the length space that is left after removing the unsealed part and the tab glue can be used by the electrode core body, and the battery capacity and energy density are improved by increasing the length of the electrode core main body.
