Novel Solid‐State Li/LiFePO4 Battery Configuration with a Ternary Nanocomposite Electrolyte for Practical Applications

Abstract

A novel ternary nanocomposite electrolyte based on an ionic liquid electrolyte immobilized in a mesoporous SiO2 matrix is demonstrated in a solid-state Li/TNCE/LiFePO4 battery configuration (see figure) to give solid-state lithium ion batteries viable for practical applications. This specific solid-state battery has the advantages of high energy/power density, good safety, low cost, flexible design, and environmental benignity.
