Abstract
A secondary battery () of the present invention includes at least a positive electrode (), a negative electrode (), a separation layer () that spatially separates the positive electrode () and the negative electrode (), and an ion conductor that is held between the positive electrode () and the negative electrode () and has a function of conducting ions between the positive electrode () and the negative electrode (). In addition, in an initial stage of using the secondary battery (), the secondary battery has a characteristic of a potential decrease rate of the positive electrode () immediately before completion of full discharging being larger than a potential increase rate of the negative electrode () immediately before the completion of full discharging and a characteristic of a potential increase rate of the positive electrode () immediately before completion of full charging being larger than a potential decrease rate of the negative electrode () immediately before the completion of full charging, and the secondary battery () is continuously used until a state in which the potential decrease rate of the positive electrode () immediately before the completion of full discharging becomes smaller than the potential increase rate of the negative electrode () immediately before the completion of full discharging.
