Abstract: A battery includes: a housing including a housing body, and a first end plate and a second end plate opposite to each other. The first end plate, the second end plate, and the housing body define an accommodating cavity. An adhesive injection port is formed on the second end plate. A battery core assembly is disposed in the accommodating cavity and includes a first surface facing an inner wall of the housing body. The second end plate and the battery core assembly are separated by a gap, and a sealing member is disposed in the gap to divide the gap into a first channel and a second channel. The adhesive injection port is in communication with the first channel. A potting channel includes the first channel and a third channel between the first surface and the inner wall. A potting adhesive is disposed in the potting channel.
