Abstract

The present application is applicable to the technical field of a battery (100), and provides a battery cell (10), the battery (100), an electrical apparatus, a combination apparatus (2100) and method, and a processing device (2000). The processing device (2000) is configured to process the battery (100), and includes the combination apparatus (2100). The combination method includes: driving the combination apparatus (2100) to combine and fix a part of a separator (113) to a first electrode plate (111) and/or a second electrode plate (112). The electrical apparatus includes the battery (100). The battery (100) includes the battery cell (10). The battery cell (10) includes an electrode assembly (11). The electrode assembly (11) includes the first electrode plate (111), the second electrode plate (112), and the separator (113). The first electrode plate (111) and the second electrode plate (112) are alternately stacked or are alternately stacked and wound. At least a part of the separator (113) is disposed between the first electrode plate (111) and the second electrode plate (112), and the part of the separator (113) is combined with and fixed to the first electrode plate (111) and/or the second electrode plate (112). In this way, only a part of the separator (113) is used for performing combination operation, and other parts of the separator (113) are not used for performing combination operation. In this way, a problem of poor overall air permeability of the separator (113) can be improved, helping to improve an ionic conducting capability of the separator (113), to improve kinetic performance of the battery cell (10).
