Symposium ES1: Materials Science and Chemistry for Grid-Scale Energy Storage

This symposium will cover recent advances in materials science and materials chemistry for grid-scale energy storage applications (other than flow batteries). As renewable energy sources become increasingly coupled to electric grids, development of high efficiency, low cost and large-scale energy storage technologies will be critical for balancing the grid system and ensuring its reliability and stability. In addition to flow batteries, several electrochemical energy storage technologies deemed promising for stationary energy storage have been developed and/or deployed for demonstration, including Li-ion batteries, lead-acid batteries, Na-metal halide batteries, Na-ion batteries, and supercapacitors. With the advance of the above technologies to different Technical Maturation Level (TML), progress has been made on materials sciences, materials chemistry, as well as materials processing and manufacturing technologies. In the past decade, significant effort has been made in the development of high capacity stable electrode materials/structures, high energy density redox couples, new electrolyte additives and solvent systems, membranes, surface modification technologies, advanced characterization tools, and new understanding of degradation chemistry and failure mechanisms. This symposium will cover most recent advances in these research areas. It also will include examples of mature development in the field, such as advanced deployment and demonstration of large scale Li-ion and Na-metal halide battery systems. Therefore, submissions are encouraged covering the wide range of materials science, materials chemistry, processing and manufacturing, device applications, theory, simulation and material/device characterization.
