Abstract: A non-woven mat may be generated using synthetic wood pulp and short glass fibers. The non-woven mat may be made in very thin, light weight configurations for various uses. The synthetic wood pulp may serve as a dispersant to disperse the glass fibers in a mixture prior to using paper making techniques to form the mat. A heat flux may bind the glass fibers by melting the synthetic wood pulp to form a mat. The mat may be calendered. In some embodiments, the mat may have a secondary application of a polymer, such as PVDF or PMMA which may further strengthen the mat.

Abstract: Polymer electrolyte composites for alkali metal electrochemical devices which are formed by coating an inert, lightweight, electrically insulating, non-woven glass fiber net which includes a polyvinyl alcohol binder, with a liquid polymer which may be ionically conductive, and curing the polymer to form a solid or semi-solid state electrolyte composite.
