Abstract: This application provides a housing, an arc battery, and an electric device. The housing includes two cover plates and a middle frame, where the two cover plates are both arc shaped plates, the middle frame has two opposite openings in a first direction, and the two cover plates are configured to respectively cover the two openings, and the middle frame and the two cover plates jointly define an accommodating space. The two cover plates of the housing are both arc plates, and therefore the housing can be used for arc batteries. The housing is divided into two are cover plates and a middle frame that are separately disposed.
