HIGH IONIC CONDUCTIVITY COMPOSITE LILAZRBIO GARNET - POLYMER ELECTROLYTE

A method of controlling the ionic conductivity of a polymer member, including providing a plurality of particles of bi-doped garnet, dispersing the plurality of particles of bi-doped garnet in a PEO matrix to yield a polymer member, nucleating spherulites at bi-doped garnet particle sites, and growing spherulites to a critical density to provide ionic conductivity pathways throughout the polymer member.
