Flexibility of paper-based-electrolytes and their mechanical properties. (a) Failure of an ionic gel electrolyte without filter paper under bending. (b) Significantly higher flexibility of a paper-based electrolyte. (c) Various shapes of paper-based electrolytes. (d) Stress-strain curves of an ionic gel electrolyte and a paper-based electrolyte. (e) Young’s modulus of an ionic gel electrolyte and a paper-based electrolyte under tensile cyclic loads at low frequencies.
