DESCRIPTION:Prof. Anton van der Ven\, UC Santa Barbara\, USA\nBatteries ar
 e extraordinary devices when viewed from the vantage point of a materials 
 scientist. They rely on the shuttling of mobile cations such as Li or Na b
 etween metallic electrodes that are separated by an electronically insulat
 ing electrolyte. This induces large swings in the cation concentration of 
 the electrode materials and often results in a variety of structural and o
 rdering phase transformations. Viable electrode materials tend to have com
 plex crystal structures\, which can lead to unique ionic transport mechani
 sms. Cathode materials are transition metal oxides and often exhibit pecul
 iar electronic and magnetic properties that vary during the course of char
 ging and discharging the battery. Furthermore\, large volume and shape cha
 nges of the electrode materials during each charge and discharge cycle can
  cause complex chemo-mechanical phenomena that need to be understood and c
 ontrolled in order to extend the lifetime of battery materials. Increasing
 ly\, modern computational approaches are being used to predict and underst
 and the intriguing electrochemical properties of battery materials. In thi
 s talk I will describe first-principles statistical mechanics methods that
  are able to predict the thermodynamic and kinetic properties of electrode
  materials for Li-ion and Na-ion batteries. These methods have shed light 
 on the link between the electronic structure of electrode materials and th
 eir electrochemical properties and have revealed a rich variety of ionic d
 iffusion mechanisms in the solid state. I will focus in particular on inte
 rcalation compounds\, commonly used as cathodes\, and lithium alloys\, whi
 ch are currently of great interest due to their ability to foster uniform 
 plating and stripping of lithium in all-solid-state batteries.\n\nBio: Ant
 on Van der Ven is Professor in Materials at UC Santa Barbara. His research
  focuses on the development and application of first-principles statistica
 l mechanics methods for the prediction of the thermodynamic and kinetic pr
 operties of metal alloys\, ceramics and semiconductor compounds. He joined
  UC Santa Barbara in 2013 after starting his academic career at the Univer
 sity of Michigan. He received his PhD from the Massachusetts Institute of 
 Technology in 2000 and continued on as a postdoctoral researcher until 200
 4. Van der Ven is the recipient of the TMS Hume-Rothery award and several 
 teaching awards.
