The invention provides a novel composition comprising a multi-ionic polyoligomeric silsesquioxane and a polyether solvent, optionally with an additional lithium salt. The composition of the invention allows for improved lithium ion transference over lithium salts alone by avoiding the problem of ion aggregation that reduces conductivity in single ion conductors. Also provided is a method for forming such a composition and a liquid electrolyte comprising a multi-ionic polyoligomeric silsesquioxane and a polyether solvent, optionally with an additional lithium salt.

The present invention provides new impact protection materials and the method of making the same. More specifically, the impact protection materials are polymer-based shear-thickening composite comprising a non-shear-thickening polymer matrix material and one or more shear-thickening materials. Preferably, the non-shear-thickening polymer matrix material is in an amount from approximately 5 weight percent to approximately 90 weight percent with the balance being one or more shear-thickening materials. The first type of the one or more shear-thickening materials is sol-gel based shear-thickening material in which small inorganic particles are connected in a gel network; the second type is polymer-based shear-thickening material in which polymer chains form network. Compared to the existing shear-thickening materials, the present shear-thickening materials have different molecular structure and formulation and possess properties of good impact protection and good stability.
