Abstract

Erfindungsgemäß werden ein Verfahren zur Herstellung von Batterieelektroden und mit diesem Verfahren hergestellte Batterieelektroden zur Verfügung gestellt, wobei das Verfahren das Herstellen von Zusammensetzungen der Elektrodenmassen für Kathoden- bzw. Anodenmasse und gegebenenfalls einer Seperatormasse und das Extrudieren der Elektrodenmasse zum Ausbilden der Anode oder Kathode aus der Elektrodenmasse umfasst, und dadurch gekennzeichnet ist, dass die Elektodenmasse Isocyanate und eine wässrige Dispersion eines Polymerbinders umfasst, die unter Ausbildung poriger Strukturen miteinander reagieren. Durch das erfindungsgemäße Verfahren entstehen äußerst elastische und zugleich mechanisch stabile Batterieelektroden, die in Lithium-Sekundärbatterien eingesetzt werden können.
