The iterative volume change of electrode materials during electrochemical charging/discharging processes could generally result in the performance degradation of electrochemical capacitors. This work investigates the mechanical stability of the electrode material during the electrochemical charging/discharging processes. which can be monitored by means of in situ dilatometry technique... https://www.roneverhart.com/SAAB-9-3-I-98-02-Frontlykt-Hoyre/
