An electric energy storage device in which a cell assembly having electrode leads is installed in a metal case. The electric energy storage device includes an internal terminal formed with a support, connection ribs and thorough portions, and the electrode leads include a part of electrode leads compressed by the support and the connection ribs of the internal terminal and a part of electrode leads located at the thorough portions of the internal terminal to maintain a shape thereof.

Electrical energy storage apparatus having improved coupling structure of internal terminal

An electric energy storage device has an inner terminal disposed in a cylindrical metal case and connected to an electrode of a bare cell, wherein the inner terminal includes a plate-shaped terminal body having a circular outer circumference; at least one electrolyte impregnation hole formed through the terminal body in a thickness direction; a flange located at the outer circumference of the terminal body and extending perpendicular to a plane of the terminal body; and a spacer formed to protrude at a periphery of at least one impregnation hole among the impregnation holes or formed by protruding a part of the plane of the terminal body.

Electric energy storage device having improved terminal structure

An electrode composition, including a conductive powder; a glass frit; and an organic vehicle including an organic binder, a multi-functional (meth)acrylate compound, and a solvent, the multi-functional (meth)acrylate compound having a molecular weight of about 200 to about 500, and being present in an amount of about 0.15 wt % to about 2 wt % based on 100 wt % of the electrode composition.
