PROBLEM TO BE SOLVED: To solve such a problem that, in conventional assembled batteries, a unit cell having an output capacity ratio (a ratio of output performance to energy capacity) that is the same as that of each of a plurality of assembled batteries is needed for the assembled batteries having different output capacity ratios with each other, but production of many kinds of unit cells goes against mass production, so that price reduction in assembled batteries is difficult.SOLUTION: An assembled battery according to the present invention is configured by connecting in series two kinds of unit cells having different electrode area densities with each other while changing the component ratio of the unit cells, so that a plurality of assembled batteries having different output capacity ratios can be configured using only two kinds of unit cells. Accordingly, unit cells can be aggregated into two kinds to enable mass production, so that price reduction can be achieved by volume efficiency thereof. |
