DESCRIPTION:Dr. Ivano Tavernelli\, IBM Zürich\nIn 2009\, IBM Research emb
 arked into an extremely challenging project\, the ultimate goal of which i
 s to deliver a new type of battery that will allow to drive an electric ve
 hicle for 500 miles without intermediate recharging. The battery considere
 d the most promising candidate to achieve this goal is based on lithium an
 d oxygen\, commonly known as Lithium/Air battery\, potentially delivering 
 energy densities one order of magnitude larger than state-of-the-art elect
 rochemical cells. ! In this talk\, I will present the results of our compu
 tational investigations for nonaqueous lithium/air electrochemical cells w
 ith particular attention to the chemical stability of different candidate 
 solvents versus solid lithium peroxide[2] and to the understanding of nove
 l solid-state lithium-ion conducting ceramics[3]. Particular emphasis will
  be given to the latest approaches combining materials science simulations
  and cognitive computing (MARVEL) to propose alternative materials with en
 hanced stability to ensure an appropriate reversible electro-chemical reac
 tion and finally contribute to the optimization of a key technology for el
 ectric vehicles.\nBibliography\n[1] T. Laino\, A. Curioni\, Chemistry: A E
