主 题：Aqueous Li/Na-ion battery Energy density Aqueous electrolyte Electrochemical stability window Hydrogen isotope effect
摘 要：Aqueous rechargeable Li/Na-ion batteries have shown promise for sustainable large-scale energy storage due to their safety,low cost,and environmental ***,practical applications of aqueous batteries are plagued by water s intrinsically narrow electrochemical stability window,which results in low energy *** this perspective article,we review several strategies to broaden the electrochemical window of aqueous electrolytes and realize high-energy aqueous ***,we highlight our recent findings on stabilizing aqueous Li storage electrochemistry using a deuterium dioxide-based aqueous electrolyte,which shows significant hydrogen isotope effects that trigger a wider electrochemical window and inhibit detrimental parasitic processes.
