Abstract:
A measuring method of a battery includes the step of measuring frequency characteristics of an internal impedance of the battery by an AC impedance method, and determining a parameter of an element representing ease of mobility of charges on a surface of a positive electrode of the battery and that of an element representing the ease of mobility of charges on the surface of a negative electrode.
