METHOD OF MAKING A FLEXIBLE SOLID ELECTROLYTE FOR USE IN SOLID STATE CELLS, FLEXIBLE SOLID ELECTROLYTE SO MADE, AND SOLID STATE CELL INCLUDING SAID FLEXIBLE SOLID ELECTROLYTE

摘要

A flexible solid electrolyte is made for use in solidstate cells by a method including the steps of:(A) mixing about 80 to 95 weight percent of powderedsolid electrolyte with about 5 to 20 weight percent of powderedTEFLON;(B) milling the mixture until the TEFLON particlesthoroughly bind the solid electrolyte powder into a stiffcoherent dough;(C) pressing the milled mixture to a thickness ofabout 1 mm;, and(D) forming a solid state cell by placing theelectrolyte sheet between two electrodes and further reducingthe cell thickness to where the electrolyte layer is lessthan 0.1 mm thick.
