Abstract
An electrochemical device and an electronic device. A packaging bag of the electrochemical device includes a main portion and a top seal portion connected together. A sealed region of the top seal portion includes an edge point Q2 close to an edge of the cell assembly and located on a first wall. The top seal portion includes the first wall extending along a first direction. A second wall of the main portion is connected to the first wall and a third wall. A connection point Q3 is formed at a junction between the second wall and the third wall. An angle R between the first wall and a straight line K1 satisfies: 80° ≤ R ≤ 110°; and/or along the first direction, a distance h between the edge point Q2 and the connection point Q3 satisfies: 0 mm ≤ h ≤ 1 mm.
