LAYER SYSTEM FOR ELECTROCHEMICAL CELLS

摘要

A layer system for electrochemical cells comprising at least one fibrous nonwoven fabric (A) formed by fibers of one or more organic polymers or mixtures of organic polymers (A1) wherein (i) the fibrous nonwoven fabric (A) contains a polymer electrolyte (C) comprising (C1) an electrolyte solvent or a mixture of electrolyte solvents, (C2) at least one electrolyte salt, and (C3) at least one organic polymer or polymer mixture, and/or (ii) a second fibrous nonwoven fabric (B) formed by fibers of one or more organic polymers or mixtures of organic polymers (B1) is aligned parallel to (A), wherein (B) may contain a polymer electrolyte (D) comprising (D1) an electrolyte solvent or a mixture of electrolyte solvents, (D2) at least one electrolyte salt, and (D3) at least one organic polymer or polymer mixture.
