More Information
Summary:A separator and/or protective layer for a lithium cell. In order to enable rapid charging of the cell and to extend the service life of the cell, the separator and/or the protective layer encompasses a copolymer and/or a polymer blend, the copolymer encompassing at least one repeating unit for constituting a polymer having a lithium-ion transference number >0.7 and at least one mechanically stabilizing repeating unit, and/or the polymer blend encompassing at least one polymer having a lithium-ion transference number >0.7 and at least one mechanically stabilizing polymer. Cells, and copolymers, polymer blends, and polymer electrolytes on the basis of polymers having a lithium-ion transference number >0.7, are also described.
