This document summarizes a presentation on solid electrolytes. It discusses how solid electrolytes exhibit ionic conductivity through mobile anions or cations, with maximum conductivity between 0.1-10 Ohm-1cm-1. Examples of solid electrolytes mentioned include AgI, β-alumina, and zirconia. Applications discussed include use in batteries, oxygen sensors, and solid oxide fuel cells. The proposed work is to synthesize and characterize Sr and Cu doped LaAlO3 as a potential solid electrolyte material.
