Decoupling of Ion-Transport From Polymer Segmental Relaxation and Higher Ionic-Conductivity in Poly(ethylene oxide)/Succinonitrile Composite Based Electrolytes Having Low Lithium Salt Doping

Only limited enhancement in room-temperature ionic-conductivity for poly(ethylene oxide), PEO, based electrolytes is possible due to coupling between ionic-conductivity and segmental relaxation. In the present study, we have achieved ionic-conductivity of 1.07 × 10
