Synergistic Enhancement of Mechanical and Electrochemical Properties in Grafted Polymer/Oxide Hybrid Electrolytes.

ABSTRACT: Lithium metal batteries operated with high voltage cathodes are predestined for the realization of high energy storage systems, where solid polymer electrolytes offer a possibility to improve battery safety. Al₂O₃_PCL is introduced as promising hybrid electrolyte made from polycaprolactone (PCL) and Al₂O₃ nanoparticles that can be prepared in a one-pot synthesis as a random mixture of linear PCL and PCL-grafted Al₂O₃. Upon grafting, synergistic effects of mechanical stability and ionic conductivity are achieved. Due to the mechanical stability, manufacture of PCL-based membranes with a thickness of 50 µm is feasible, yielding an ionic conductivity of 5·10^-5 S cm^-1 at 60 °C. The membrane exhibits an impr
