Abstract
An electric energy storage device includes a positive electrode internal terminal composed of a plate-shaped terminal body having at least one electrolyte impregnation hole formed therein and a flange, wherein an upper surface of the terminal body and any one surface of the flange come into contact with a cell assembly to couple the positive electrode internal terminal and the cell assembly, wherein a lower surface of the terminal body comes into contact with an inner surface of a lower end of a case, and wherein the flange is pressed by a terminal-fixing beading portion so that the positive electrode internal terminal is fixed in the case.
