Abstract

An electrochemical device and an electronic device are disclosed. The electrochemical device includes a housing, an electrode assembly, a first conductive plate, a first layer, and a second layer. The housing includes a first wall and a side wall. The electrode assembly is a wound structure and includes a first electrode sheet. The first conductive plate includes a first conductive area and a second conductive area, connected to the first electrode sheet and the first wall, respectively. The second conductive area extends in a second direction and includes a first end portion connected to the first conductive area and a second end portion opposite the first end portion. In a first direction, the first layer is disposed between the electrode assembly and the second conductive area. When viewed from the first direction, the first layer includes a first side extending in a curved manner along an edge of the electrode assembly and a second side connected to the first side, where the second side overlaps with the electrode assembly, and the second side is farther from the edge of the electrode assembly than the first side to form a notch. When viewed from the first direction, the second end portion overlaps with the first layer, and a first area of the second layer overlaps with the first layer. This application can improve reliability and service life.
