}Brief summary
Solid-state batteries promise to be safer, store more energy and last longer than today's batteries, and the solid electrolyte is at their heart. This review explains what is known about how inorganic solid electrolytes conduct ions, how they behave electrochemically and mechanically, and how they are made, and identifies the main hurdles: metal anodes, unstable interfaces and keeping physical contact.
Full abstract
In the critical area of sustainable energy storage, solid-state batteries have attracted considerable attention due to their potential safety, energy-density and cycle-life benefits. This Review describes recent progress in the fundamental understanding of inorganic solid electrolytes, which lie at the heart of the solid-state battery concept, by addressing key issues in the areas of multiscale ion transport, electrochemical and mechanical properties, and current processing routes. The main electrolyte related challenges for practical solid-state devices include utilization of metal anodes, stabilization of interfaces and the main tenance of physical contact, the solutions to which hinge on gaining greater knowledge of the underlying properties of solid electrolyte materials.
