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.

Electrochemical device and electronic device containing same

A housing is disclosed, including an accommodating cavity, where a surface of the housing is provided with a groove, a thickness of an area provided with the groove in the housing is less than a thickness of an area provided with no groove in the housing, the housing further includes a protective layer, and the protective layer is disposed on the surface of the housing and covers an opening end of the groove. The groove helps discharge a pressure from the housing, and the protective layer can prevent the housing from being accidentally broken. This application further provides a battery to which the housing is applied, and an electronic apparatus to which the battery is applied.

Housing, battery, and electronic apparatus

A battery includes a casing assembly which includes a terminal post and a first casing. The first casing includes a first casing portion and a second casing portion connected to the first casing portion. The first casing portion protrudes from the second casing portion to define a receiving space. The terminal post is fixed to the first casing portion and partially received in the receiving space. A battery including the battery casing assembly is further provided.
