Fabrication and Characterization of Layer-by-Layer Structured PEO/PVP/NaClO4 based Solid Polymer Electrolyte Membranes

Currently, solid polymer electrolyte membranes (SPEMs) are receiving much attention owing to their intriguing characteristic properties in comparison to the potentially dangerous liquid electrolytes.1, 2 Note that, single ion conducting polymers demonstrate low conductivity and mobility at room temperature due to their dependence on polymer segmental motion. In order to overcome this problem, we propose a novel layer-by-layer structured polymer membranes and to check their adaptability as a promising solid electrolyte in sodium ion conducting batteries.
