Paper Abstract

We develop theoretical model based on a general thermodynamic theory of the stress-composition interaction. The electromechanical responses are investigated by means of electrochemical impedance spectroscopy and bending displacement measurements. The model takes into account the electrochemical stress due to the intercalation (de-intercalation) process which generates the strain and bending of the actuators. The relationship between the strains and the real part of the complex capacitance by introducing the strain-capacitance coefficient ξC was analyzed.
