Yunsong and Qi overcame several computational challenges and developed a half-cell model in order to compute the Li+ + e- → Li0 charge transfer reaction with quantum precision. This process governs the performance of the lithium (Li)-ion batteries, but is extremely difficult to probe experimentally. With two years of dedicated work, along with the development of DFTB parameters for Li-metal and Li-ion (J. Phys. Chem. C 2018, 122, 20, 10755-10764) , we fianlly revealed the detailes of energy and charge variations across the Li/SEI/electrolyte interface during Li stripping and plating. The paper, "Energy landscape of the charge transfer reaction at the complex Li/SEI/electrolyte interface", was published on Energy Environ. Sci.,2019,12, 1286-1295
