Abstract:

Limited by the decomposition voltage of water (1.23 V), the open-circuit voltage of aqueous secondary batteries is generally low. Through the analysis of factors influencing the open-circuit voltage of aqueous secondary batteries, several new strategies to improve the open-circuit voltage are introduced in this paper. In addition, the advantages and disadvantages of each strategy are discussed.
