Electrochemical cell comprising (A) at least one anode as component (A), (B) at least one cathode as component (B), (C) at least one non-aqueous electrolyte as component (C), (D) at least one separator positioned between anode (A) and cathode (B), as component (D), characterized in that separator (D) is manufactured from at least one polyimide selected from reaction products of (a)at least one polyimide selected from condensation products of (alpha) at least one polyisocyanate having on average at least two isocyanate groups per molecule and (beta) at least one polycarboxylic acid having at least3 COOH groups per molecule or an anhydride or ester thereof, and (b) at least one diol or triol, and subsequently optionally reacted with (c) at least one polyisocyanate having on average at least two isocyanate groups per molecule. |
