Solid Electrolytes for Lithium Batteries

Abstract

With the continuous consumption of non-renewable energy and the need to restrict carbon dioxide emissions, development and breakthroughs in lithium secondary batteries have become one of the most important areas for research. Among lithium secondary batteries, the solid-state lithium battery is deemed to be the next generation for energy storage equipment on account of its long cycle number, higher discharge specific capacity, and higher safety. As an important part of solid-state lithium-ion metal batteries, solid electrolytes need to have excellent mechanical properties, better ionic conductivity, and strong stability. Chapter 6 introduces research progress for different types of solid electrolytes, including oxide solid electrolytes, sulfide solid electrolytes, and phosphate solid electrolytes. The characteristics of these solid electrolytes are summarized, and directions for the future development of solid electrolytes are provided.
