Title: Fabrication of films and coatings used to activate shear thickening, impact resistant electrolytes

Abstract

A method of making a passively impact resistant composite electrolyte and separator layer includes providing a suspension composition including electrically non-conducting particles that enable shear thickening. The particles can have a polydispersity index of no greater than 0.1, an average particle size in a range of from 50 nm to 1 um, and an absolute zeta potential of greater than ±40 mV. A particle suspension solvent is provided for suspending the particles. The suspension composition is applied to a porous separator material. A portion of the particles and suspension solvent penetrate the pores and the remainder of the particles in the suspension composition are distributed across the surface of the separator material. The suspension solvent is evaporated from the separator material to provide a shear thickening particle loaded separator. A separator assembly and a passivated battery are also disclosed.
