Abstract: Reusable filters for personal protective equipment (PPE) may prevent shortages of PPE and save fabrication time, resources, and money. Disclosed is a method and system for fabrication of nanofiber filter media for PPE. The method includes positioning a substrate to receive nanofibers thereon, providing a voltage gradient in a region of the substrate, and electrospinning nanofibers onto the substrate. The methods and associated systems allow autoclaving of the filter medium at temperatures of up to 300 degrees for sanitizing the filter medium. Additionally, the methods and associated system allow for the inclusion of an anti-pathogen agent in the nanofiber filter media.

Abstract: A cathode for a multilayer solid-state electrochemical cell is described herein. The cathode comprises nanofibers of a cathode active material; particles of the cathode active material; and nanofibers of a cubic phase lithium lanthanum zirconium oxide (c-LLZO); all of which are dispersed in a polymeric matrix. Electrochemical cells comprising a solid-state electrolyte and the cathodes comprising the nanofibers of c-LLZO are also described herein.
