DESCRIPTION:Rechargeable batteries have been a great success in powering c
 onsumer electronics. There has been a recent strong interest in applying r
 echargeable batteries to vehicle electrification and grid- scale storage. 
 Novel battery chemistries are necessary for enabling these opportunities a
 lthough they also present significant fundamental materials challenges. He
 re I will present the exciting progress in my group for the past decade on
  exploring nanomaterials design to address these challenges. Examples incl
 ude: 1) High capacity battery electrode materials such as Si\, Li metal an
 d P anodes and S cathodes\; 2) Low-cost grid scale energy storage chemistr
 ies: Li polysulfide and Prussian blue open framework materials\; 3) Smart 
 battery separators for safety enhancement. Based on the principle of batte
 ry reaction\, we discovered that it can be used as a powerful way to elect
 rochemically tune electrocatalysts\, resulting in significant improvement 
 of catalytic activity for hydrogen and oxygen evolution reactions.
