<p>PROBLEM TO BE SOLVED: To solve such a problem that reduction of price is difficult when producing unit cells, required in the small-lot-and-multi-kind set battery, while matching to respective output capacity ratios, because the unit cells are produced by high-mix low-volume.SOLUTION: Since a set battery is constituted of two kinds of unit cells having different electrode facing area density, it is inevitably constituted of two kinds of unit cells having significant different output capacity ratio. Consequently, a set battery having an appropriate output capacity ratio can be provided by production of only two kinds of unit cells, even for the small-lot-and-multi-kind battery application. Since mass production of unit cells is possible, price of the small-lot-and-multi-kind battery can be reduced by mass production effect.</p> |
