ABSTRACT: The unique fundamental mechanism that dominates interface reaction in a solid-state battery becomes the design opportunity to unlock many breakthrough performances beyond commercial Li-ion batteries. The talk discusses how electrochemical interface reactions are locally coupled with mechanical and transport properties to dictate battery performance, giving opportunities to design electrolyte and electrode coating materials for advanced battery performance.

BIO: Professor Xin Li is an associate professor of materials science at Harvard John A. Paulson School of Engineering and Applied Sciences. Xin Li’s research group (scholar.harvard.edu/lixin) designs new energy-related materials and systems through advanced synthesis, characterization, and simulation, with the current focus on Li and Na ion batteries, solid-state batteries, and unconventional superconductors. Xin Li received his B.S. degree in physics from Nanjing University, China, his Ph.D. degree in materials science and engineering at Pennsylvania State University and performed postdoctoral research at CalTech and MIT before joining Harvard in 2015. Prof. Li is also a cofounder of Adden Energy, Inc (www.addenenergy.com), which is a solid-state battery start-up company aiming at combating climate-change with next-generation battery technologies.
