“…In order to validate the performance of isomeric catalysts in Zn-air battery, these molecules anchored on CNT were utilized as the OER catalysts during the charge chemistry in tri-electrode ZAB configuration as shown in ( Scheme S1 ) ( Cao et al., 2013 ) ( Tran et al., 2020 ) ( Hong et al., 2016 ). The discharge chemistry was carried out between Zn electrode and a Pt/C-based ORR catalyst and the charge chemistry was carried out between the Zn electrode and the isomeric catalysts.…”

The pursuit of green and sustainable energy is a long-term goal for modern society and people's life. Particularly under the context of carbon neutralization, decarbonization has become a consensus and propels the turning of research enthusiasm to explore new materials and chemistries for energy conversion and storage at a low expenditure. Zinc (Zn) enabled redox flow batteries (RFBs) are competitive candidates to fulfill the requirements of largescale energy storage at the power generation side and customer end. Considering the explosive growth, this review summarizes recent advances in material chemistry for zinc-based RFBs, covering the cathodic redox pairs of metal ions, chalcogens, halogens, and organic molecules. After a brief introduction of common issues for Zn 2+ /Zn conversion reaction at the anode side, the focus is devoted to expounding challenges of redox species and possible problem-solving strategies at the cathode side. Besides, the auxiliary components of separator and current collector are also discussed for achieving optimal RFBs' performance. At last, the conclusion and outlook of future endeavor for Zn-based RFBs implementation are put forward.

“…6,7 However, there still are unavoidable problems hindering the development of ZABs such as selfcorrosion and passivation effect of the zinc anode. 8 The formation of zinc oxide during working is one of the reasons that obstructs the ZABs' work by decreasing the utilization efficiency of zinc and diminishing battery life for a long time. 9 It has been revealed that zinc oxide generates an electrolyte during the ORR and aggregates into a film to cover the zinc anode.…”

Strategy of Electrolyte Design: Triethanolamine as a Polydentate Ligand to Improve Solvation of Zinc in Zinc–Air Batteries

et al. 2023

The zinc−air batteries (ZABs) are regarded as the most potential energy storage device for the next generation. However, the zinc anode passivation and hydrogen evolution reaction (HER) in alkaline electrolyte situations inhibit the zinc plate working efficiency, which needs to improve zinc solvation and better electrolyte strategy. In this work, we propose a design of new electrolyte by using a polydentate ligand to stabilize the zinc ion divorced from the zinc anode. The formation of the passivation film is suppressed greatly, compared to the traditional electrolyte. The characterization result presents that the quantity of the passivation film is reduced to nearly 33% of pure KOH result. Besides, triethanolamine (TEA) as an anionic surfactant inhibits the HER effect to improve the efficiency of the zinc anode. The discharging and recycling test indicates that the specific capacity of the battery with the effect of TEA is improved to nearly 85 mA h/cm 2 compared to 0.21 mA h/cm 2 in 0.5 mol/L KOH, which is 350 times the result of the blank group. The electrochemical analysis results also indicate that zinc anode self-corrosion is palliated. With density function theory, calculation results prove the new complex existence and structure in electrolytes by the data of the molecular orbital (highest occupied molecular orbital−lowest unoccupied molecular orbital). A new theory of multi-dentate ligand inhibiting passivation is elicited and provides a new direction for ZABs' electrolyte design.
