Electrochemical device and electronic device

Abstract

An electrochemical device includes an electrode assembly, a packaging shell, and an adhesive component. The packaging shell includes a main portion and a seal edge portion. The electrode assembly is disposed in the main portion. The seal edge portion includes a first section and a second section that are folded. The second section includes a first end and a second end. The first section connects the main portion and the first end. The second end is disposed between the first section and a lateral edge of the main portion. The adhesive component is adhered between the lateral edge of the main portion and the second section. The second section is connected to the adhesive component. Along a thickness direction of the electrode assembly, an end of the adhesive component extends beyond the second end of the second section, and the adhesive component wraps the second end.
