Abstract

The present application is applicable to the technical field of batteries (100), and provides a battery cell (10), a battery (100), an electric apparatus, and a device (2000) and method for processing a battery (100). The battery cell (10) includes an electrode assembly (11). The electrode assembly (11) includes a positive electrode sheet (111), a negative electrode sheet (112), and a separator (113). The positive electrode sheet (111), the negative electrode sheet (112) and the separator (113) are stacked or wound. Some portions of the separator (113) protrude beyond an edge of the positive electrode sheet (111) and an edge of the negative electrode sheet (112) to form edge sealing portions (1131); and some of the edge sealing portions (1131) are fixedly connected. In this way, the separator (113) can stably and reliably wrap the positive electrode sheet (111) and the negative electrode sheet (112), alleviating the problem of overlapping of the positive electrode sheet (111) and the negative electrode sheet (112) caused by folding of the separator (113), thereby improving the reliability of the battery cell (10).
