Polymer gel electrolytes for application in aluminum deposition and rechargeable aluminum ion batteries

Abstract

Polymer gel electrolyte using AlCl3 complexed acrylamide as functional monomer and ionic liquids based on acidic mixture of 1-ethyl-3-methylimidazolium chloride (EMImCl) and AlCl3 as plasticizer has been successfully prepared for the first time by free radical polymerization. Aluminum deposition is successfully obtained with a polymer gel membrane contianing 80 wt% ionic liquid. The polymer gel membranes are also good candidates for rechargeable aluminum ion batteries.
