STORAGE BATTERY AND POWER STORAGE DEVICE

WIPO Patent Application WO/2023/175698

A1

The present invention makes it possible to reduce component count and to charge/discharge in different operating voltage ranges. A storage battery according to the present invention comprises a first electrode that has positive or negative polarity, a second electrode that has the same polarity as the first electrode, and a shared electrode that has the opposite polarity from the first and second electrodes. The first electrode has a first collector foil and first active material layers that are formed on the respective surfaces of the first collector foil. The second electrode has a second collector foil and second active material layers that are formed on the respective surfaces of the second collector foil and have a different operating voltage from that of the first active material layers. The shared electrode is positioned between the first electrode and the second electrode, and has a shared collector foil in which a plurality of through holes have been formed and shared active material layers which are formed on the respective surfaces of the shared collector foil. The storage battery also comprises a first external terminal that is connected to the first electrode, a second external terminal that is connected to the second electrode, and a shared external terminal that is connected to the shared electrode.
