Symposium EN05-Chemomechanical and Interfacial Challenges in Energy Storage and Conversion—Batteries and Fuel Cells

Interfacial chemistry and mechanics interplay at the nanometric scale and collectively govern the functionalities of redox active materials. Understanding the relationship between the two can inform the design of materials electrochemistry with optimal chemomechanical properties for long-life and reliable energy devices. Electrochemical reactions involve constant mass and charge transport across the electrode and electrolyte interfaces. These transport processes can introduce formation of interfacial species, defects and phase transformation in the vicinity of the interface. Extensive interfacial reactions can ultimately lead to the chemical and structural transformation at the length scale beyond the interface and through the bulk of participating materials. The reversibility of these processes essentially governs the performance metrics (e.g., efficiency, life, energy, power) of these devices. In the last few years, we have witnessed a huge wave of fundamental studies in unraveling the interfacial materials electrochemistry and its relationship with the chemomechanical properties. The rapid advancement of in situ characterization tools has enriched the community’s understanding of chemomechanical and interfacial challenges, and a number of successful characterization-driven discoveries have been reported in this domain. Specifically, synchrotron X-ray techniques stand out as one of the most effective methods that allows for nearly nondestructive probing of materials characteristics such as electronic and geometric structures with various depth sensitivities through spectroscopy, scattering, and imaging capabilities. These characterization tools are complemented by the state of the art electron and neutron spectroscopy and microscopy. The symposium will highlight current progress of advanced experimental and computational methodologies in understanding and improving the chemomechanical and interfacial properties of electrochemical materials for energy storage and conversion. It is intended to bring experts from materials science, chemistry, engineering and mechanics interested in energy conversion, and storage to review current state of art and formulate the outstanding research needs and grand challenges in the chemomechanical and interfacial properties in advanced electrochemical energy materials.
