Impact resistant compositions and apparatuses, and methods of producing the same

Abstract

Embodiments described herein relate to passively impact-resistant porous assemblies, electrochemical cells incorporating these assemblies, and methods for their manufacture. The assembly includes a porous substrate having a surface and defining pores therein, and a plurality of shear thickening particles. A first portion of the plurality of shear thickening particles is disposed on or over the surface, and a second portion is disposed at least partially in the pores. The second portion includes less than 10% of the total mass of the first and second portions of the shear thickening particles. Upon impact, the plurality of shear thickening particles can form agglomerates while suspended in a liquid or semi-liquid composition, causing to increase in viscosity of the liquid composition, thereby enhancing durability and impact resistance.
