Abstract
Dynamic materials processes such as phase
transformations, corrosion, and nucleation/growth can play key roles during operation of devices for electrochemical
energy storage and conversion; often, these processes are not well understood at the nanoscale. In situ experiments,
which involve characterization of materials under realistic electrochemical environments, can provide unique insight
into the operation of materials within devices. This talk will show how in situ transmission electron microscopy (TEM) and other ex situ techniques have revealed
important nanoscale transformation and degradation mechanisms in two different electrochemical systems, lithiumāion
batteries and solar fuels devices. Together, the results demonstrate the importance of understanding materials behavior
in energy systems, and they provide guidelines for engineering improved electrochemical devices.
