BATTERY, ELECTRIC DEVICE AND MANUFACTURING METHOD FOR BATTERY

Disclosed is a battery (100), an electric apparatus, and a manufacturing method of the battery (100), related to the technical field of batteries. The battery (100) includes a plurality of battery cells (110) and a mounting base (130), where the plurality of battery cells (110) are electrically connected; the mounting base (130) is used to fix an output electrode (150) of the battery (100), the output electrode (150) is used to export electric energy of the plurality of battery cells (110), the mounting base (130) includes at least one limiting surface (1311), and the limiting surface (1311) is matched with the contour of the battery cell (110). Through the battery (100), the electric apparatus, and the manufacturing method of the battery (100), the occupied space of the mounting base (130) is reduced, and the energy density of the battery (100) is increased.
