Boric acid is used as electrolyte additive for lead-acid battery in the current research. The working mechanism of the boric acid additive is studied thoroughly. The boric acid can participate in the electrochemical reactions directly. The battery with boric acid exhibit prolonged cycling performance due to the improved anti-corrosion properties.
AN has been reported as anti-freeze additive . The anti-freezing electrolyte can be obtained by adding AN into the 1 M Zn (CF 3 SO 3) 2 . This hybrid electrolyte can improve the redox kinetics and alleviate the concentration polarization of Zn 2+ (Fig. 6 a). Moreover, the electrolyte possesses a low freezing point of -55.3 ℃.
Therefore, the Zn/V 2 O 5 batteries present a good cycling stability with only 0.56% capacity decay per cycle for 2000 cycles at -20 ℃. In addition, other alcohols, such as methanol, glycerol, and sorbitol have been also shown to be effective anti-freeze additives [55,,,,, 85].
Anti-freezing additives have the characteristics of "small dosage" and "quick effect". They could greatly reduce the freezing point of the electrolyte, and eliminate interface side reactions, which would significantly improve the electrochemical performance of AZIBs at low-temperature conditions.
Therefore, as shown in Fig. 3, there are three main mechanisms for improving the anti-freezing property of aqueous electrolytes, including breaking the free water hydrogen bonds, confining the free water hydrogen bonds, and reducing the free water content.
