Abstract: A battery, including a laminated cell, a first housing configured to accommodate the laminated cell, and a second housing mounted to the first housing, where the laminated cell includes an electrode assembly and a first tab. The electrode assembly includes a first side face, where the first tab is connected to the first side face, and the first housing, the first tab, and the first side face together define an injection space. The second housing is provided with an injection opening, where a projection of the injection space onto the second housing covers at least part of the injection opening. This application further provides an electric apparatus with the foregoing battery. This application can improve injection efficiency.
