Abstract
A polymeric solid electrolyte, a method of preparing the same, and an all-solid-state battery comprising the same is described. More specifically, the safety and ionic conductivity of the polymeric solid electrolyte can be simultaneously improved by improving the mobility of the polymer chains by blending a liquid polyhedral oligomeric silsesquioxane (POSS) and a single ion conductor.
