Abstract
A conventional secondary battery has a problem that an internal resistance is very high in a low SOC region and necessary output cannot be taken out. In a secondary battery including a positive electrode and a negative electrode, a capacity difference from a terminal potential of a positive electrode discharge curve to a terminal voltage of a battery discharge curve of the secondary battery with respect to a discharge capacity of the secondary battery is 14% to 26%.
