Abstract: An electrochemical device includes a packaging shell having a first packaging body provided with a first dent and a first flange connected to a sidewall of the first dent, and a second packaging body provided with a second dent and a second flange connected to a sidewall of the second dent; a first electrode assembly disposed in the first dent; a second electrode assembly disposed in the second dent; and a partition plate including a partition layer and a first bonding layer located on a first surface of the partition layer. The partition plate is located between the first packaging body and the second packaging body. The flange overlaps the partition plate and extends beyond an edge of the partition plate. The partition plate fits with the first packaging body and the second packaging body to form mutually independent cavities on two sides of the partition plate.

Abstract: This application provides a housing, an arc battery, and an electric device. The housing includes two cover plates and a middle frame, where the two cover plates are both arc shaped plates, the middle frame has two opposite openings in a first direction, and the two cover plates are configured to respectively cover the two openings, and the middle frame and the two cover plates jointly define an accommodating space. The two cover plates of the housing are both arc plates, and therefore the housing can be used for arc batteries. The housing is divided into two are cover plates and a middle frame that are separately disposed.

Abstract: An electrochemical device and an electronic device containing the electrochemical device. With a first accommodation portion disposed in the electrochemical device, a specific accommodation space is provided for a bend portion of a first tab, thereby avoiding a need to additionally increasing space for accommodating the bend portion, where the space is originally intended for accommodating the electrode assembly. This effectively saves the space occupied by the tab in the packaging shell, reduces the size of the electrochemical device, and improves an energy density of the electrochemical device. The electronic device also achieves a high energy density.
