Influence of Nickel Introduction into Alumina Filler on the Ion Conduction of Polymer Electrolyte

Abstract

An attempt has been made to prepare γ-alumina containing nickel in framework by a solution process, and to apply the nickel-containing alumina for filler in polymer electrolyte based on poly(ethylene oxide). The obtained polymer electrolyte exhibits higher conductivity than those without filler and with alumina filler in particular at temperature lower than 45°C, while the mobility of lithium ion appears to be similar regardless of the existence of nickel in alumina filler. This attempt has exhibited that the ceramic particles containing transition metal species can be used as effective fillers for the improvement of transport properties of polymer electrolytes.
