A cap assembly includes a current interrupt portion; a cap-up electrically connected with the current interrupt portion; and a gasket fixing the current interrupt portion and the cap-up, wherein the current interrupt portion comprises a vent portion comprising a safety vent configured to fracture when a predetermined pressure is applied thereon, and a cap-down comprising at least one hole configured to allow gas to flow in a direction toward the cap-up; and wherein an overall area of the at least one hole is about 0.12% to about 1.61% of a cross-sectional area of the gasket based on an outer diameter of the gasket.

Cap assembly and secondary battery including the same

A Plasma Display Panel (PDP) includes a dielectric layer having a plurality of dielectric-layer perforated holes arranged in a matrix; upper and lower electrode layers each having electrode-layer perforated holes connected to the dielectric-layer perforated holes and arranged on both surfaces of the dielectric layer, the upper and lower electrode layers being adapted to receive electrical signals. The upper electrode layer includes a plurality of upper electrodes extending in a first direction, each of the plurality of upper electrodes surrounding a group of the electrode-layer perforated holes arranged in the first direction and including transparent individual electrodes surrounding the electrode-layer perforated holes and linear connection portions adapted to electrically connect the individual electrodes. The lower electrode layer includes a plurality of lower electrodes extending in a second direction at an angle with respect to the first direction, each of the plurality of second electrodes surrounding a group of electrode-layer perforated holes arranged in the second direction.
