Abstract (en)

[origin: WO2017093107A1] The invention relates to a separator and/or to a protective layer (4) for a lithium cell (1). In order to permit fast charging of the cell (1) and to prolong the service life of the cell (1), the separator and/or the protective layer (4) comprise a copolymer and/or a polymer mixture, wherein the copolymer comprises at least one repetition unit for forming a polymer having a lithium iron transference number > 0.7 and at least one mechanically stabilizing repetition unit, and/or wherein the polymer mixture comprises at least one polymer having a lithium ion transference number > 0.7 and at least one mechanically stabilizing polymer. The invention further relates to cells and to copolymers, polymer mixtures, and polymer electrolytes based on polymers having a lithium iron transference number > 0.7.
