ELECTROLYTE SEPARATOR WITH EXCELLENT BRITTLENESS AND STORAGE PROPERTY IN WHICH LITHIUM EUTECTIC MOLTEN SALTS ARE DENSELY DIPPED WITHIN THE PORES OF A POROUS SiOC THIN FILM AND A FABRICATION METHOD THEREOF

摘要

PURPOSE: An electrolyte separator is provided to ensure strong brittleness and easy handling property and to prepare a battery having excellent properties using an SiOC thin film on the non-woven fabric without the reactivity with ternary eutectic salts(LiCl-LiBr-LiF).;CONSTITUTION: An electrolyte separator comprises a porous SiOC thin film and a lithium eutectic salt dipped within the pores of the porous SiOC thin film. The lithium eutectic salt is LiCl-LiBr-LiF. A method for preparing the electrolyte separator comprises the steps of: (i) applying electrolyte powder to a orous SiOC thin film; (ii) forming an electrolyte molten material by melting the electrolyte powder through the heating of the porous SiOC thin film to which the electrolyte powder is applied; and (iii) dipping the electrolyte molten material in the pores of the porous SiOC thin film.;COPYRIGHT KIPO 2012
