Hydro energy storage systems have attracted much attention due to advantages such as high security, low cost, and environmental compatibility. However, the specific chemical properties of water cause the problems of narrow electrochemical stability window, low stability of water-electrode interface reactions, and dissolution of electrode materials and intermediate products; Therefore, new low-cost aqueous electrolytes with different water chemistry are needed. The nature of water largely depends on its hydroxyl-based hydrogen bonding structure; Therefore, ultraconcentrated hydroxyl-rich sugar solutions are designed to alter the original hydrogen bond structure of water. Ultra-concentrated...
