a cap plate, said cap plate perforated by an orifice; a nonconductive glass metal tube inserted into the orifice of said cap plate, said tube being hollow and being formed of a gelled mixture of a particulate glass and metal, the mixture being hardened by heat to form the glass metal tube; a pin inserted through said tube, said tube, said cap plate and said pin being atomically bonded together along their respective contact areas; and a ring positioned to surround the orifice and terminate one end of said tube and separate the cap plate from a head of the pin that terminates the pin, and laterally opposite sides of the ring respectively engaging the head of the pin and an edge of the cap plate defining a periphery of the orifice, respectively. ### Claim 2 (depends on 1) The cap assembly of claim 1, the battery comprising a rectangular secondary battery. ### Claim 3 (depends on 1) The cap assembly of claim 1, comprised of said ring comprising a flange of said tube extending radially outwardly from the orifice. ### Claim 4 (depends on 1) The cap assembly of claim 1, said ring comprising a ceramic unit fitted at one side of said cap plate to extend radially outwardly from the orifice and to cover a base surface of the tube and obstruct direct contact between said cap plate and the head terminating said pin. ### Claim 5 (depends on 4) The cap assembly of claim 4, wherein said head further comprises: a deformation portion protruding at an end of said pin, said deformation portion being deformed when said pin is inserted into said tube, said deformation portion establishing an area for connection with a tab of the battery. ### Claim 6 (depends on 5) The cap assembly of claim 5, said deformation portion securely fixing a position of said pin when said deforming is performed. ### Claim 7 (depends on 1) The cap assembly of claim 1, wherein said head father comprises: a deformation portion protruding at an end of said pin, said deformation portion being deformed when said pin is inserted into said tube, said deformation portion establishing an area for connection with a tab of the battery. ### Claim 8 (depends on 7) The cap assembly of claim 7, said deformation portion securely fixing a position of said pin when said deforming is performed. ### Claim 9 (depends on 4) The cap assembly of claim 4, wherein said tube, said cap plate and said pin are atomically bonded together along their respective contact areas by high-temperature heating being performed in a range of 400 to 1000 degrees Celsius (° C.). ### Claim 10 A battery, comprising: an electrode plate assembly formed by winding a positive electrode and a negative electrode separated by a separator; a battery case for accommodating said electrode plate assembly; and a cap assembly; said cap assembly comprising: a cap plate, said cap plate perforated by an orifice, said cap plate hermetically sealing said battery case; a nonconductive tube inserted through the orifice of said cap plate, said tube being a hollow and being formed of glass and metal; a pin terminated by a head, the pin being inserted through said tube said cap plate, said tube, and said pin being atomically bonded together at their respective contact areas by high-temperature heating; and a ring positioned to extend beyond a junction formed by a periphery of the orifice and the cap plate and terminate one end of said tube and separate the cap plate from a head of the pin that terminates the pin, and laterally opposite sides of the ring respectively engaging the head of the pin and an edge of the cap plate defining a periphery of the orifice, respectively. ### Claim 11 (depends on 10) The battery of claim 10, said tube having a low-melting point. ### Claim 12 (depends on 11) The battery of claim 11, the battery comprising a rectangular secondary battery, and said battery case being rectangular in shape. ### Claim 13 (depends on 10) The battery of claim 10, further comprising: a tab of the battery, said tab being coupled to one of the positive electrode and the negative electrode; and a deformation portion protruding at an end of said pin, said deformation portion being deformed when said pin is inserted into said tube, said deformation portion establishing an area for connection with said tab to establish an electrical connection between said tab and said pin. ### Claim 14 (depends on 13) The battery of claim 13, said deformation portion securely fixing a position of Said pin when said deforming is performed. ### Claim 15 (depends on 14) The battery of claim 14, said tube having a low-melting point. ### Claim 16 (depends on 15) The battery of claim 15, the battery comprising a rectangular secondary battery, and said battery case being rectangular in shape. ### Claim 17 (depends on 1) The cap assembly of claim 1, wherein said ring is selected from the group consisting of a ceramic ring and a flange encircling said tube. ### Claim 18 (depends on 1) The cap assembly of claim 1, said cap plate, said tube and said pin being bonded together at their contact areas by heating. ### Claim 19 (depends on 10) The battery of claim 10, wherein said ceramic unit is selected from the group consisting of a ceramic ring and a ceramic sheet. ### Claim 20 (depends on 10) The battery of claim 10, said cap plate, said tube and said pin being bonded together at their contact areas by heating.
