Abstract

A secondary battery and an electronic device are provided. The secondary battery includes a housing, an electrode assembly disposed in the housing, and a first conductive plate. The electrode assembly is a stacked structure. The electrode assembly includes a first electrode plate, a separator, and a second electrode plate that are stacked sequentially in a first direction. The first conductive plate is connected to the first electrode plate. The first conductive plate extends out of the housing along a second direction perpendicular to the first direction. The first electrode plate includes a first outer electrode plate located at an outermost layer of the electrode assembly. When viewed in a third direction perpendicular to both the first direction and the second direction, the first outer electrode plate includes a first region and a second region connected in the second direction. When viewed in the third direction, the first region includes a first end connected to the second region and a second end disposed opposite to the first end in the second direction. The first region extends from the first end so as to deviate from the second direction, and the second end is farther away from the second electrode plate in the first direction than the first end. This application improves anti-overcharge performance.
