摘要： A stack type battery has a stacked electrode assembly (10) in which a plurality of positive electrode plates (1) and a plurality of negative electrode plates (2) are alternately stacked one another across separators. Each one of pairs of the separators adjacent to each other in a stacking direction has a bonded portion (4) in which the separators are bonded to each other in at least a portion of a perimeter portion thereof, so as to form a pouch-type separator (3). The proportion of the bonded portion (4) of one of the pouch-type separators 3 (low blocking rate pouch-type separator (3L)) located in a stacking direction-wise central region of the stacked electrode assembly (10) is made smaller than the proportion of the bonded portion (4) of each of the pouch-type separators 3 (high blocking rate pouch-type separator 3H) located in both stacking direction-wise end portions of the stacked electrode assembly (10).

摘要： 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.

摘要： Stacked positive and negative electrode current collector tabs are bundled respectively in such a manner as to be gathered at one stacking direction-wise side (the upper end side) of the stacked electrode assembly. Portions of the bundled tabs extending from the bundled portion toward a tip side of the bundled tabs are bent toward the other stacking direction-wise side (lower end side) of the stacked electrode assembly, to form bent portions. The stacked electrode assembly is covered and fixed by an insulating sheet having insulation capability so as to cover both stacking direction-wise end faces thereof and surround the stacked electrode assembly in a tubular shape. A portion (slip-in piece) of the insulating sheet is inserted between the stacked electrode assembly and the bent portions of the positive and negative electrode current collector tabs. A portion (outer cover piece) of the insulating sheet covers the bent portions of the positive and negative electrode current collector tabs from outside.

摘要： 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.
