Development of all-solid-state mediator-enhanced supercapacitors with polyvin…

Abstract. All-solid-state supercapacitors (SCs) were fabricated using a polyvinylidene fluoride (PVDF)/lithium trifluoromethanesulfonate (LiTFS) membrane as the separator and poly(ethylene oxide) (PEO)/lithium perchlorate (LiClO4) as the polymer electrolyte in the porous carbon electrodes. Two types of mediators, NaI/I2 and K3Fe(CN)6/K4Fe(CN)6, were added into the PEO/LiClO4 polymer electro…
