DE- AC05–76RL01830. The SEM, TEM, Raman and XPS measurements were performed using EMSL (grid.436923.9), a DOE Office of Science User Facility sponsored by the Office of Biological and Environmental Research located at Pacific Northwest National Laboratory (PNNL). PNNL is operated by Battelle for the DOE under Contract DE-AC05–76RL01830. The LiFSI salt was provided by Dr. Kazuhiko Murata of Nippon Shokubai Co., Ltd.
