Abstract: Provided is a stacked electrode assembly including: a lowermost electrode arranged on a lowermost portion of the stacked electrode assembly; an uppermost electrode arranged on an uppermost portion of the stacked electrode assembly; at least one unit stacked body arranged between the lowermost electrode and the uppermost electrode and including a positive electrode, a negative electrode, and a separator, the separator being arranged between the positive electrode and the negative electrode; and a separator arranged between the lowermost electrode and the at least one unit stacked body, and between the at least one unit stacked body and the uppermost electrode. A capacity and energy density of a lithium battery may be improved by employing an electrode including a mesh electrode current collector as the lowermost electrode or the uppermost electrode of the stacked electrode assembly.

Abstract: The aid robot for transporting according to the present invention comprises a driving portion driven electrically by operating a switch; an elevating portion which is coupled to the driving portion and of which a height is adjustable; and a weight support portion which is coupled to the elevating portion so that a tilt of the weight support portion is adjustable, and formed so that its width become narrower and then wider reversely towards the bottom to piggyback the user, wherein the weight support portion comprises a support part at the bottom where the user's bottom is seated, and a wing part at the top for supporting the user's armpits. According to the aid robot for transporting, the weight support portion has a structure that the user can be easily piggybacked thereby reducing time to seat on.
