Summary: In this study, Ti3C2Tx MXene is shown to operate at a wide potential range in a mild AlCl3 aqueous electrolyte and retain high pseudocapacitive activity, achieving a capacity of up to 85 mAh g(-1), surpassing its performance in H2SO4 electrolyte of 78 mAh g(-1). In situ electrochemical quartz crystal microbalance results suggest that the high capacity originates from the pseudocapacitive intercalation/deintercalation of H+ instead of Al3+, providing the possibility of coupling MXene anodes with proton redox active cathodes to achieve high-energy and high-power devices.

Summary: Aqueous electrolytes are essential for batteries due to their sustainability, greenness, and low cost. However, the reactivity of water molecules with alkali metals limits the use of high-capacity alkali-metal anodes. In this study, water molecules are confined in a carcerand-like network to create quasi-solid aqueous electrolytes (QAEs) that effectively overcome the limitations of free water molecules. The QAEs allow stable operation with alkali-metal anodes, suppressing issues such as dendrite growth, electrode dissolution, and polysulfide shuttle. The research demonstrates long-term cycling and high Coulombic efficiency of alkali-metal cells in a water-based environment, as well as the potential of full metal batteries with remarkable energy density.
