A solid-state electrolyte with reliable electrochemical performance, mechanical robustness and safety features is strongly pursued to facilitate the progress of flexible batteries. Here, we demonstrate a shape-deformable and thermally stable plastic crystal composite polymer electrolyte (denoted as “PC-CPE”) Journal of Materials Chemistry A Hot Articles Flexible energy storage and. Electrochemical Engineering provides a reference for scientists and engineers working with electrochemical processes, and a rigorous, thorough text for graduate students and upper-division undergraduates. Merging theoretical concepts with widespread application, this book is designed to provide critical knowledge in a real-world context.
Therefore, the polymer electrolyte films were instead prepared by mixing the dry polyketone and salt, followed by hot-pressing. To use this method, it is necessary to know the melting point and the thermal stability of the polymer. TGA analysis showed that the polymer is stable from room temperature up to around °C, as can be seen in Fig Author: Therese Eriksson, Amber Mace, Yumehiro Manabe, Masahiro Yoshizawa-Fujita, Yasuhide Inokuma, Daniel B. Figure 9 graphically presents the multifunctional performance of these materials in comparison to the performance of other structural polymer electrolytes from earlier studies. To simplify the comparison, the trusses presented in this study are composed of the same structural materials and backfilled with the same electrolyte materials as those Cited by: 1.
