摘要: The present invention relates to separators for electrochemical cells comprising(A) at least one layer comprising (a) crosslinked polyvinylpyrrolidone in the form of particles, (b) at least one binder, and (c) optionally a base structure, where the mass ratio of the crosslinked polyvinylpyrrolidone in the form of particles (a) to the sum of the mass of the binders (b) in the layer (A) has a value in the range from 99.9:0.1 to 50:50. The present invention further relates to the use of inventive separators and to apparatuses, especially electrochemical cells, comprising inventive separators.

摘要: A separator with a main part which is made of nonwoven material, and is provided with a coating. The coating contains filler particles, cellulose, and flexible organic binder particles. The filler particles and flexible organic binder particles are connected to each other by the cellulose. Such a separator exhibits high permeability with increased mechanical stability. The cellulose of the separator contains cellulose derivatives that have a chain length of at least 100 repeating units, preferably a chain length of at least 200 repeating units.
