    Abstract: An explosion-proof valve includes a valve body that includes a connection section at an edge of the valve body and a scored groove, and an opening region on a radial inner side of the connection section. A shape of an orthographic projection of the valve body and a shape of an orthographic projection of the opening region in a depth direction of the scored groove are non-circular. An outer edge of the orthographic projection of the opening region is an opening boundary. An area of the orthographic projection of the opening region is Sopen, an area of an orthographic projection of the connection section is g Sconnect, and an area of the orthographic projection of the valve body is Stotal, where Sopen, Sconnect, and Stotal meeting: 10%

    Abstract: A battery case is provided, including a plurality of side plates. A first side plate has the largest area among the plurality of side plates, and at least one first side plate includes a first portion and a second portion. The first portion is a curved surface concave toward inside of the battery case. A three-dimensional coordinate system is established in a first direction, a second direction, and a third direction, and the second direction is perpendicular to the first side plate. A curvature of the first portion is less than a curvature of an ellipsoid, the curvature of the ellipsoid is obtained from an ellipsoid function, and the ellipsoid function is: ((x−a)/i)2+((y−b)/j)2+((z−c)/k)2=1, where, a, b, c, i, j, and k are determined according to coordinates of at least four points that are different from each other, and x, y, and z are coordinates of the three directions of the ellipsoid function.

    Abstract: A cell includes a housing and at least one electrode core assembly array encapsulated inside the housing. The electrode core assembly array includes N rows and M columns of electrode core assemblies, and the electrode core assembly includes an encapsulation film and at least one electrode core encapsulated inside the encapsulation film. The electrode core assemblies are arranged in rows, and each row includes M electrode core assemblies. The electrode core assemblies are arranged in columns, and each column includes N electrode core assemblies. The N electrode core assemblies in each column are connected in series to form an electrode core assembly string. The M electrode core assembly strings are connected in series. An air pressure between the metal housing and the encapsulation film is lower than an air pressure outside the metal housing.
