Jafta, Xiao-Guang Sun, Craig Bridges, and co-workers use high surface area mesoporous hard carbons to demonstrate that surface passivation for the bis(fluorosulfonyl)imide anion (FSI SP - sp ) occurs via chemical reactions at the open cell voltage, and through electrochemical reactions at cell voltages near 2 V. The research provides insight into the design of anions for stable inorganic salt passivation of electrode interfaces in next generation batteries. [Extracted from the article]
