20090246607 | LAMINATE TYPE BATTERY AND BATTERY MODULE INCORPORATING THE LAMINATE TYPE BATTERY - A laminate type battery includes a laminate battery case and an electrode assembly. The laminate battery case includes two laminate films each having a metal layer and plastic layers provided on both faces of the metal layer, and has a welded portion in which peripheral edges of the two laminate films are welded to each other. The electrode assembly is enclosed in the laminate battery case, and has a positive electrode plate, a negative electrode plate, and a separator disposed therebetween. An internal gas pressure sensing portion, in which the inner plastic layer of each of the laminate films is absent and the metal layers are in contact with each other so as to be in an electrically conductive state, is formed in a portion of the welded portion. A voltage detection hole, in which the outer plastic layer is absent and the metal layer is exposed, is formed in a surface of each of the two laminate films. | 10-01-2009 |

20120003528 | SQUARE-CELL BATTERY AND MANUFACTURING METHOD FOR SAME - The present invention aims to provide a battery that includes electrode terminals passing through a lid, in which the lid and electrode terminals are securely insulated and sealed while being solidly fixed to each other without using an insulation-forming body or packing. To this end, a lid has upwardly-protruding protrusions formed therein. Through-holes are formed in the protrusions and tapered so as to become narrower toward the top relative to the bottom. Fitting portions forming the middle portions of a cathode terminal board and an anode terminal board are tapered to fit into the through-holes. Heat-welding tape is introduced between the outer faces of the fitting portions and the inner faces of the through-holes. The heat-welding tape is made up of an insulating substrate with heat-welding layers layered on both sides thereof. | 01-05-2012 |
20120028100 | PRISMATIC SECONDARY BATTERY - A prismatic secondary battery is a prismatic lithium-ion battery including a stack-type electrode assembly in which square positive and negative electrode plates are stacked with separators interposed therebetween. The positive electrode plates are arranged inside a bag-like separator. The width of the separator protruding from an end portion of each positive electrode plate on a non-joined side of the separator is greater than that of the separator protruding from an end portion of the positive electrode plate on a joined side of the separator. The heat-shrinkage rate of the separator in a direction vertical to the non-joined side is greater than that of the separator in a direction parallel to the non-joined side. Short circuiting between the positive and negative electrode plates due to heat shrinkage or rupture of the separator is prevented even when abnormal heat generation occurs in the battery. | 02-02-2012 |
