Conductivity of Polyacrylonitrile Based Lithium Polymer Electrolytes
Abstract
Preparation of solid state polymer lithium electrolytes based on polyacrylonitrile (PAN) have achieved room temperature conductivities equal to that of liquid organic electrolytes. Polymer films of ethylene carbonate, propylene carbonate, PAN, and lithium salts have yielded conductivities as high as 0.004 S/cm at 25 deg C. These high conductivities make the use of polymer electrolytes a viable possibility in advanced batteries. Reported here are film preparation technique, conductivities from -70 to 70 deg C, and Vogel-Tammann- Fulcher (VTF) relationships.
