Title: Next Generation Solid-Electrolytes and Cathode Design for All Solid-State Batteries

Abstract:   Lithium-metal based solid-state batteries (SSB) are considered to  the holy-grail of the  next generation battery technology for their promise of higher energy density (500 Wh/Kg), safety and providing a flexible platform for integrating a number of promising solid-electrolytes (SE) with  high capacity cathodes using either a thin lithium metal or anode free configuration. The design rule for achieving high energy and fast charge SSB will be discussed with specific focus on sulfide and halide based solid-electrolytes. Most of the sulfide-based SE compositions such as Li3PS4 and Argyrodite (LiPS5X; X= Cl, Br) are thermodynamically unstable against high voltage cathodes such as NMC and hence are not best catholyte for solid-state cathodes. On the contrary, halide SEs have higher oxidative stability but poor stability with respect to Li-metal. The talk will also cover development of thin SE membranes (50 micron) for integration with cathodes and development of Na-ion based SE.
