A complex hydride lithium superionic conductor for high-energy-density all-solid-state lithium metal batteries

Abstract

All-solid-state batteries could deliver high energy densities without using organic liquid electrolytes. Here the authors report a complex hydride Li-ion conductor 0.7Li(CB9H10)–0.3Li(CB11H12) that exhibits impressive ionic conductivity and other electrochemical characteristics in an all-solid-state cell.
