Abstract
A cell includes a metal housing and multiple electrode core strings encapsulated in the metal housing. The multiple electrode core strings are arranged in a second direction and sequentially connected in series. Each of the electrode core strings includes an encapsulation film and multiple electrode core assemblies arranged in a first direction and sequentially connected in series. The electrode core assemblies are encapsulated in the encapsulation film. An air pressure between the metal housing and the encapsulation film is lower than an air pressure outside the metal housing.
