“…Of the reported SSEs, the highest ionic conductivity is 0.8 mS • cm −1 , measured for an ionic liquid with active fillers, created by Shirshova et al [124]. [95,121,124,131,132].…”

“…Interestingly, when the thermoplastic polymer was mixed with the active filler LiTf and no epoxy was added, the best mechanical and electrochemical properties were observed, suggesting the potential use of thermoplastic electrolytes for SSEs [134]. This approach was further studied by Joyal et al, who created a single-phase solid polymer electrolyte by mixing the thermoplastic polymer polyethylene terephthalate with the lithium salt LiClO 4 [131], achieving the highest reported Young's modulus of 2100 MPa but also the lowest ionic conductivity of 1 mS • cm −1 . However, the use of thermoplastic polymers as a base for SSEs does not only suggest potential in terms of mechanical and electrochemical properties but also in terms of processability.…”

Structural supercapacitors (SSCs) are multifunctional energy storage composites (MESCs) that combine the mechanical properties of fiber-reinforced polymers and the electrochemical performance of supercapacitors to reduce the overall mass in lightweight applications with electrical energy consumption. These novel MESCs have huge potentials, and their properties have improved dramatically since their introduction in the early 2000’s. However, the current properties of SSCs are not sufficient for complete energy supply of electrically driven devices. To overcome this drawback, the aim of the current study is to identify key areas for enhancement of the multifunctional performance of SSCs. Critical modification paths for the SSC constituents are systematically analyzed. Special focus is given to the improvement of carbon fiber-based electrodes, the selection of structural electrolytes and the implementation of separators for the development of more efficient SSCs. Finally, current SSCs are compared in terms of their multifunctionality including material combinations and modifications.

“…For example, by blending DGEBA with different proportions of succinonitrile and lithium salt, the ionic conductivity of the resulting electrolytes varied from 1 × 10 -3 mS/cm to 0.1 mS/cm and Young's modulus from 1 GPa to 10 MPa, respectively [122]. Other examples of solid electrolytes include those based on cellulose acetate [123], PVA [124] and polyethylene terephthalate (PET) [125]. Finally, composite solid electrolytes should be considered, which consist of active or passive inorganic fillers and polymer matrices.…”

Structural supercapacitors that simultaneously bear mechanical loads and store electrical energy have exciting potential for enhancing the efficiency of various mobile systems. However, a significant hurdle in developing practical structural supercapacitors is the inherent trade‐off between their mechanical properties and electrochemical capabilities, particularly within their electrolytes. This study demonstrates a tough polymer electrolyte with enhanced multifunctionality made through the controlled hydration of a solid polymer electrolyte with poly(lactic acid) (PLA) and lithium salts. Characterization via differential scanning calorimetry, X‐ray diffraction, and Fourier transform infrared spectroscopy confirms the consistent amorphous solid solution phase in varying salt concentrations, whether dried or hydrated. Electrochemical tests and tensile tests are performed to evaluate the ionic conductivity and mechanical properties of these electrolytes. The results indicate that the strategic incorporation of water in the polymer electrolyte significantly enhances the ionic conductivity while preserving its mechanical properties. A specific composition demonstrated a remarkable increase in ionic conductivity (3.11 µS cm−1) coupled with superior toughness (15.4 MJ m−3), significantly surpassing the base polymer. These findings open new horizons for integrating electrochemical functionality into structural polymers without compromising their mechanical properties. Additionally, the paper reports the successful fabrication and testing of structural supercapacitor prototypes combining carbon fibers with fabricated electrolytes, showcasing their potential for diverse applications.
