An Introduction to Solid Polymer Electrolytes
Among the two broad classes of solid electrolytes, inorganic ceramics currently offer the highest room-temperature conductivities (10⁻³–10⁻² S cm⁻¹) but demand high-temperature sintering, are mechanically brittle, and suffer from large interfacial impedance with composite electrode [1]. Solid polymer electrolytes (SPEs), such as polyethylene oxide (PEO)–LiTFSI, polycarbonates, and block-copolymer systems, trade some conductivity (10⁻⁵–10⁻³ S cm⁻¹ … Read more
