NICHT-WIEDERAUFLADBARE DÜNNSCHICHTBATTERIEN MIT KATIONISCH-FUNKTIONALISIERTEN POLYMEREN ALS SEPARATOREN

The present invention relates to a thin-film battery, comprising: a. at least one flat negative electrode as component (A), b. at least one flat positive electrode as component (B), c. at least one electrolyte as component (C), and d. at least one flat separator, which is arranged between the at least one negative electrode (A) and the at least one positive electrode (B), as component (D), wherein the at least one separator (D) contains at least one cationically functionalized polymer, a method for production of said thin-film battery by joining together at least one negative electrode as component (A), at least one positive electrode as component (B), an electrolyte as component (C) and at least one separator as component (D), wherein the at least one separator contains at least one polymer which has been functionalized with cationic groups, the use of polymers which have been functionalized with cationic groups as a separator in thin-film batteries, and the use of a thin-film battery according to the invention in electronic components.
