Description:Abstract:\n\nBatteries have transformed our daily lives and hol
 d the key to a low carbon future. Yet\, current Li-ion chemistries are app
 roaching their theoretical performance limit. Remarkably\, we continue to 
 rely on a limited subset of Li-ion battery materials –– most commercia
 l cathodes derive from LiCoO2 developed in 1980 –– that cannot meet o
 ur ever-growing need for energy storage. The development of more sustainab
 le\, energy dense\, and safer batteries hinges on designing new cathode ch
 emistries and crystal structures that depart from the traditional layered 
 lithium transition metal oxides\, as well as non flammable solid electroly
 tes.\n\nIn this talk\, I will present our work combining solid-state NMR\,
  first principles simulations\, and other advanced tools to relate synthes
 is\, structure\, and properties in various classes of battery materials. F
 or example\, our work on Li-ion rocksalt oxyfluoride cathodes emphasizes t
 he importance of 7Li/19F solid-state NMR to determine the true composition
  of such systems and establish robust materials design rules\, and introdu
 ces a new\, rapid and energy-efficient synthesis procedure to obtain those
  materials. I will also present our work on weberite-type Na-ion cathodes\
 , which offer an attractive alternative to the lithium technology\, partic
 ularly when combined with Earth-abundant redox-active species such as iron
 . Finally\, I will discuss our work on Li- and Na-ion conducting rocksalt 
 halide solid electrolytes\, highlighting their high propensity for polymor
 phism and for the formation of planar defects\, with resulting structural 
 and ion conduction properties that can be modulated by changing the synthe
 sis conditions.\n\n&nbsp\;\n\nAbout the Speaker: \n\nRaphaële Clément i
 s an Assistant Professor in the Materials Department at the University of 
 California Santa Barbara since 2018. She received her Ph.D. in Chemistry i
 n 2016 from the University of Cambridge\, working under the supervision of
  Prof. Clare Grey. She then joined the group of Prof. Gerbrand Ceder as a 
 postdoc at the University of California Berkeley. At UCSB\, the Clément g
 roup is interested in establishing materials design rules\, and in optimiz
 ing materials processing approaches to advance electrochemical energy stor
 age. The group’s expertise lies in the development and deployment of mag
 netic resonance techniques (experimental and computational) for the study 
 of battery materials and beyond\, with a strong emphasis on operando tools
 . She received an NSF CAREER award in 2022\, the Materials Today Rising St
 ar Award in 2023\, as well as the ISE Prize in Electrochemical Materials S
 cience from the International Society of Electrochemistry. She is a Topica
