Functional materials for next-generation Lithium batteries
Solid state batteries, Li-rich cathode materials
Overview
Energy storage systems with enhanced safety and energy density that store renewable energy and power EVs are necessary to achieve a low-carbon society. Solid-state electrolytes are developed to improve the safety of Lithium batteries. High-capacity cathodes are explored to improve their energy density.
Novelty and originality
• A scalable liquid-phase process is used to prepare high ionic conductive and nano-sized sulfide-based solid electrolytes.
• The unexpected high air stability of Li3PS4-LiI solid electrolytes is uncovered
• Solid electrolyte coating on active materials enables its full utilization in solid-state batteries
Details
Sulfide electrolytes with high ionic conductivity, small particle size, and high air stability are prepared by a scalable solution synthesis and applied to solid state batteries. The use of Li-rich cathode materials holds promise to enhance the energy density of solid-state batteries further.
Summary
• Liquid-phase processes are proposed for the industrial scaling-up of sulfide solid electrolytes.
• Solid state batteries with enhanced safety are expected to power future electric vehicles.
