Reversible anion intercalation into graphite from aluminum perchlorate “water‐in‐salt” electrolyte

Original language description

We demonstrate a highly concentrated “water-in-salt” electrolyte of aluminum perchlorate that demonstrates a wide electrochemical stability window of 4.0 V. The “water-in-salt” electrolyte suppresses the dissociation of water at high potentials, facilitating a stable and reversible perchlorate (ClO4−) anion intercalation into the graphite with a Coulombic efficiency of over 95% for more than 2000 cycles. The structural and chemical changes of the anion-intercalated graphite are studied by Operando Raman, Operando X-ray diffraction, and X-ray photoelectron spectroscopy. Our study provides an insight into ClO4− anion intercalation into graphite in the supersaturated aluminum perchlorate “water-in-salt” electrolyte, demonstrating a suitable platform for future high-voltage aqueous energy storage systems.
