Can anthraquinone-based flow batteries be commercialized?
Paired with a Fe (CN) 63−/4− positive electrolyte, the anthraquinone cell exhibited a record low capacity fade rate of <1% per year. The new synthetic strategy for these highly stable anthraquinone negolytes might facilitate the commercialization of anthraquinone-based flow batteries.
Does anthraquinone contribute to battery specific capacity?
Nonetheless, the contribution of anthraquinone structural unit to battery specific capacity is not the main factor since almost all the conjugate units would make contributions, such as anthraquinone, triazine, and benzene (Buyukcakir et al., 2020).
What are the advantages of anthraquinone derivatives?
Anthraquinone derivatives have demonstrated their high structural diversity (e.g., abundant and tunable functional groups), superior electrochemical performances (such as enhanced electrochemical stability, high active-material utilization and facilitated redox kinetics).
What are the aqueous solubility limits of anthraquinone derivatives?
Although computational studies have predicted aqueous solubility limits of anthraquinone derivatives in the range of 2–6M , other constraints linked to battery operation such as ionic conductivity, viscosity and water balance limit the concentration of anthraquinones in RFB application.
How to improve the solubility of anthraquinones in basic medium?
Several strategies can be used to improve the solubility of anthraquinones in basic medium: the introduction of solubilizing groups, a judicious choice of the counter-cation and the addition of a solubilizing compound.
Do anthraquinone-based electrolytes have different molecular lifetimes?
Furthermore, our previous research showed that the molecular lifetimes of anthraquinone-based electrolytes can differ by two orders of magnitude depending on the positions of their functional groups (e.g., 1,8- and 2,6-anthraquinones). 1619 Therefore, it is important to quantify the stabilities of organic molecules with a mixture of isomers.
