LAMINATE CELL, ASSEMBLED BATTERY, BATTERY MODULE AND ELECTRIC VEHICLE
A laminate cell comprises a power generating element formed by sequentially stacking positive electrode plates and negative electrode plates while interposing separators therebetween; a positive tab connected to the positive electrode plates through a plurality of positive leads; a negative tab connected to the negative electrode plates through a plurality of negative leads; and a cell package formed of a metal composite film, the cell package hermetically sealing the power generating element and an electrolyte. According to the laminate cell, the heat capacity of a portion of the positive tab, onto which a plurality of the positive leads are joined, and the heat capacity of a portion of the negative tab, onto which a plurality of the negative leads are joined, are made larger than that of other portions of the positive tab and the negative tab.
