Abstract: A curved battery includes an arc protection member and a battery unit. The battery unit is disposed in the arc protection member and has a shape corresponding to the arc protection member. The battery unit includes a first electrode layer, a second electrode layer, a conductive material, a first conductive handle and a second conductive handle. The battery unit is winded from one end away from the first conductive handle and the second conductive handle towards directions of the first conductive handle and the second conductive handle. The first conductive handle and the second conductive handle point to directions perpendicular to an axial direction of the battery unit and extend out of the arc protection member via two openings of the arc protection member. Thus, the curved battery is allowed with a large curvature that is less likely to cause damages of the battery unit.
