Title: New Battery Chemistries and Materials Issues (16:30-17:00)
Hybrid anion- and cation-redox (HACR) cathodes that combine the redox capacities of transition-metal cations and oxygen/sulfur anions [1] provide new opportunities for rechargeable batteries. High-voltage electrolytes and coatings [2] reduce the stress-corrosion cracking (SCC) of electrodes and the depletion of liquid electrolytes, to prolong the cycle life. New developments in Lithium-metal batteries with mixed ionic-electronic conductor (MIEC) porous interlayers and ion-electron insulator (IEI) binders will be discussed [3]. Finally, the challenges with “renewable wastes” will be introduced, and microwave based treatments will be discussed [4].
