Abstract

Abstract : In this study, we demonstrate enhanced moisture repulsion of aqueous processed ceramic coated separators inspired by the distributed wax domain on a plant leaf surface. Abstract : Biomimetic approaches in the preparation of components for lithium-ion batteries can provide new solutions to current challenging issues. We demonstrate the facile fabrication of a ceramic-coated separator (CCS) that exhibits enhanced moisture repulsion despite the use of an aqueous coating solution in the preparation. The hydrophobic character of the surface increased with the amount of micron-scale wax domain on the surface without deteriorating the charge and discharge cycle performance of the cell equipped with new CCSs.
