Abstract
A power storage device has a first power storage unit, a second power storage unit, a third power storage unit, and a fourth power storage unit. The power storage device is provided with a common electrode being integrated molding to make the first power storage unit and the second power storage unit connected in series, the third power storage unit and the fourth power storage unit connected in series, the first power storage unit and the third power storage unit connected in parallel, and the second power storage unit and the fourth power storage unit connected in parallel, so inside of the power storage device can have high potential and high capacitance, and avoid the problem of increasing the overall impedance caused by the conventional welding process. Further, the power storage device uses both surfaces of the common electrode at the same time to save electrode material.
