Original Abstract Submitted

An assembled battery includes a plurality of electrodes each including; a current collector; a negative-electrode composite layer disposed on one surface of the current collector; and a positive-electrode composite layer on the other surface of the current collector, the electrodes being stacked alternately with an electrolyte layer interposed between the electrodes, and a basis weight (mg/cm) of a negative-electrode composite material or a positive-electrode composite material in the negative-electrode composite layer or the positive-electrode composite layer of each of the electrodes located at upper positions in a stacking direction of the assembled battery is larger than a basis weight (mg/cm) of a negative-electrode composite material or a positive-electrode composite material in the negative-electrode composite layer or the positive-electrode composite layer of each of the electrodes located at lower positions in the stacking direction of the assembled battery.
