A passively impact resistant composite electrolyte composition includes an electrolyte solvent, up to 6M of an electrolyte salt, and shear thickening ceramic particles having an outer surface. The shear thickening ceramic particles have an absolute zeta potential of greater than ±40 mV. The shear thickening ceramic particles have a polydispersity index of no greater than 0.1, and an average particle size of in a range of 50 nm to 1 um. The ceramic particles have bonded to the outer surface steric stabilizing polymers. The steric stabilizing polymers have a chain length of from 0.5 nm to 100 nm. A passively impact resistant laminated battery and a method of making the electrolyte composition are also disclosed.
