Ion-conducting behavior and all-solid-state full cell performance. a Ionic conductivities and b Arrhenius plots and corresponding activation energies of PVH and PVH-IM. c Comparison of σ and E_a of PVH-IM with previously reported SPEs [24–26, 29–31, 49–51, 53, 54, 58–60]. d ${\mathit{\text{t}}}_{{\mathit{\text{Li}}}^{+}}$, e crystallinities, f Raman spectra, and g contents of free TFSI.⁻, CIP, and AGG of PVH and PVH-IM. h Rate capability at different current densities and cycling stability at the current density of i 0.1C and j 0.5C of all-solid-state LFP|PVH|Li and LFP|PVH-IM|Li full cells. k Cycling performance of all-solid-state LFP|PVH-IM|Li pouch cells at the current density of 0.1C. l Photographs showing LED bulbs powered by all-solid-state LFP|PVH-IM|Li pouch cells under different testing states: flat, folded, unfolded, and cut. All tests are conducted at 25 °C unless otherwise stated. The crystallinities in c are calculated from the corresponding DSC curves in Fig. S22
