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

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. AlO_PCL is introduced as promising hybrid electrolyte made from polycaprolactone (PCL) and AlO nanoparticles that can be prepared in a one-pot synthesis as a random mixture of linear PCL and PCL-grafted AlO. Upon grafting, synergistic effects of mechanical stability and ionic conductivity are achieved.
