Abstract: An electric suitcase includes a box body, a steering device, and pedal devices. The steering device includes a steering supporting base that is T-shaped. Handles are respectively disposed on left and right sides of the steering supporting base. First inclined portions each with an inclined surface facing downward are respectively disposed on left and right ends of the steering supporting base. Second inclined portions are respectively defined on the handles. The second inclined portions are one-to-one attached to the first inclined portions. The pedal devices include pedal fixing bases. A pedal body is plugged into each of the pedal fixing bases. Each pedal body is slidable with respect to a corresponding one of the pedal fixing bases. A pedal limiting mechanism is disposed on a bottom portion of each of the pedal fixing bases. A foot button is disposed on a top portion of each pedal body.

Abstract: A current collector, an electrode sheet, and a fabrication method for a current collector are disclosed. The current collector includes a support layer, a first electrically conductive layer and a second electrically conductive layer. The support layer has a first surface and a second surface arranged opposite to each other. The first electrically conductive layer has a grid structure distributed on the first surface and/or the second surface of the support layer. The second electrically conductive layer is provided on a surface of the first electrically conductive layer away from the support layer.
