DESCRIPTION:This talk will start by describing existing battery technologi
 es\, what some of the current and more long-term challenges are\, and touc
 h on strategies to address some of the issues.  I will then focus on my ow
 n work – together with my research group and collaborators – to develo
 p new characterisation (NMR\, MRI\, and X-ray diffraction and optical) met
 hods that allow batteries to be studied while they are operating (i.e.\, o
 perando). These techniques allow transformations of the various cell compo
 nents to be followed under realistic conditions without having to disassem
 ble and take apart the cell. We can detect key side reactions involving th
 e various battery materials\, in order to determine the processes that are
  responsible ultimately for battery failure.  We can watch ions diffusing 
 in\, and moving in and out of\, the active “electrode” materials that 
 store the (lithium) ions and the electrons\, to understand how the batteri
 es function.  Finally\, I will discuss the challenges in designing batteri
 es that can be rapidly charged and discharged.
