 e Grey FRS (Geoffrey Moorhouse Gibson Professor of Chemistry) \n‘Underst
 anding battery function - new metrologies\, new chemistries and new insigh
 ts’.\n\nRechargeable batteries have been an integral part of the portabl
 e electronics revolution and are now playing a critical role in transport 
 and grid applications to help mitigate climate change.  However\, these ap
 plications come with different sets of challenges. New technologies are be
 ing investigated and fundamental science is key to producing non-increment
 al advances and to develop new strategies for energy storage and conversio
 n.  \n\nThis talk will focus on our own work to develop NMR\, MRI and new 
 optical methods that allow devices to be probed while they are operating\,
  from the local\, to particle and then cell level. This allows transformat
 ions of the various cell materials to be followed under realistic conditio
 ns without having to disassemble and take apart the cell. Starting with lo
 cal structure and dynamics\, as measured by NMR\, I will then show - with 
 the optical methods - how the different dynamics can result in different i
 ntercalation mechanisms. A good example is our work on LiCoO2\, where via 
 optical approaches we were able to directly visualize movement of phase fr
 onts as lithium is removed and inserted into this material. I will discuss
  our work on the application of electron spin resonance and dynamic nuclea
 r polarization (DNP) NMR to graphitic anode materials and lithium metal ba
 tteries\, to understand battery degradation.  Finally\, new results on ext
 remely high-rate batteries will be outlined and extensions of our new metr
 ologies to study a wider range of electrochemical systems will be describe
