Pathways to Improved Performance of Electrochemical Systems Through an Understanding of Dynamic Materials Processes - Matt McDowell
From Katie Gentilello on February 28th, 2017
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, lithium‐ion 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.
