Abstract
The dimensions of an electrode group in each battery are set so as to obtain a relationship such as H >L>W, where H is the height of the electrode group, L is the width thereof and W is the thickness thereof, and the product K of the width L and the thickness W, that is, K=L.times.W, is set so as to fall in a range 10<K<100 while the space D between adjacent batteries is set so as to fall in a range of 0.02.ltoreq.D/W.ltoreq.0.3, thereby the efficiency of heat radiation of a battery module or a battery group is enhanced, and accordingly, the cycle life and the discharge capacity of the battery can be enhanced.
