DESCRIPTION:Dr Zhuojun Huang\nLithium-based batteries are essential in mod
 ern energy supply systems. There is a demand for safer and higher energy d
 ensity batteries\, and for securing the supply chain of Li for production 
 of these batteries. In this talk\, I will cover experimental and modeling 
 studies that focus on the interactions among ions\, solvents\, and polymer
 s in both battery and separation systems\, and how these interactions can 
 be optimized through molecular-scale design.\nThe first part introduces a 
 novel class of polymer-based electrolytes called SAFE (Solvent-Anchored no
 n-Flammable Electrolyte)\, highlighting the molecular design principles th
 at address the safety challenges of conventional electrolytes. The second 
 part discusses the combination of molecular dynamics modeling and experime
 ntal characterization to develop polymer coatings that stabilize high ener
 gy density lithium-metal electrodes\, revealing key physical and chemical 
 design principles. The final part combines high-resolution equilibrium mea
 surements with thermodynamic modeling to uncover the molecular principles 
 governing the selective separation of lithium over sodium and potassium in
  cation exchange membranes.\n \n\n© 2024 EPFL\n\n\n\n
