Structural Supercapacitors (SSC) are an important group of Multifunctional Energy Storage Composites (MESC) and can potentially play a significant role in lightweight design of aerospace and automotive applications [1]. Therefore, it is important to build accurate models based on the multiphysics involved in these electrical energy storage devices (compare e.g. [2]). As integrated structural parts, an SSC will need to retain its electrochemical performance (e.g. specific capacitance) under mechanical loads. Considering the mechanical-electrochemical coupling in SSC, there is a lack of studies analyzing the effect of mechanical stress on the electrochemical behavior of SSC, as experimentally investigated by
