Chemistry and Morphology of Liquids and Interphases for Energy Applications: an In-situ Soft X-ray Approach

- a workshop of 2015 Advanced Light Source Users Meeting

Organizers: Cheng Wang, Wanli Yang, Jinghua Guo, Ethan Crumlin, Howard Padmore, Zahid Hussain (ALS), Arun Devaraj, Vijayakumar Murugesan,  Louis J Terminello (PNNL)

Time: October 6, 13:30PM - October 7, 17:30PM 2014 (PCT)
Location: Lawrence Berkeley National Laborotary (View Map)
Conference Room: Building 15, Conference Room 253

Energy generation and storage applications rely on high-performance electrochemical devices. One of the grand challenges for the next generation energy storage is to understand and develop the complex liquid electrolytes in regards to the durability and safe performance in the electrochemical devices. The interface and interphase region between the electrolyte and electrode in an electrochemical device is the key for understanding and improving the practical performance. State-of-the-art soft x-ray spectroscopy provides unique opportunities to tackle both the physical states and chemical reactions of the electrolyte and electrolyte-electrode interface/interphase. And the newly developed RSoXS scattering technique at the ALS combines soft x-ray spectroscopy with x-ray scattering and offers statistical information for 3D chemical morphology over a large sample area.
This workshop focuses on studying both the chemistry and morphology of the critical electrolyte and interphase in electrochemical devices, solar fuel membrane assembly, and fuel-cell membranes, through in-situ/operando soft x-ray spectroscopy and scattering techniques. Our goal is to stimulate the collaborations between material scientists and spectroscopists to tackle both the fundamental and technoological challenges on the liquid-solid interface and interphase in energy devices.

NOTE: Presentations are NOT limited to synchrotron applications. Discussions on grand challenges in a broad field are highly encouraged in this workshop.
