In water splitting, the oxygen evolution reaction (OER) is the rate-determining step. To overcome the high overpotential and slow kinetics of OER, the development of effective catalysts to improve electrolysis efficiency is essential. Nickel–iron-layered double hydroxides (NiFe-LDHs) have been recognized for their superior electrochemical performance under alkaline OER conditions and have emerged as promising catalysts owing to their unique structure that enhances electrolyte infiltration and exposes more active sites. However, the unique modulation of the crystalline structure of NiFe-LDHs can further improve OER performance. Accordingly, this study introduces an innovative synthesis approach based on Zn doping and selective Zn etching to increase the ECSA and induce favorable transition-metal oxidation states in NiFe-LDHs, thereby improving OER efficiency. After 6 h of Zn etching (Ni_2.9Zn_0.1Fe-6h), the optimized Ni_2.9Zn_0.1Fe LDH sample demonstrated remarkable electrochemical performance and stability, requiring small overpotentials of 192 and 260 mV at current densities of 10 and 100 mA cm⁻², respectively. Moreover, the Ni_2.9Zn_0.1Fe-6h electrode could maintain its original overpotential (260 mV) at a current density of 100 mA cm⁻² for 250 h. The proposed Zn doping and subsequent partial Zn etching can practically be applied to numerous high-performance transition metal–based electrochemical catalysts.</p>","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.70012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144581809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While there has been notable advancement in the development of anolytes, there has been a lack of focus on the catholyte component. In this study, we present a novel all-alkaline AORFB that utilizes a highly soluble catholyte based on manganese (Mn). The formulated combination of catholyte, MnO₄^–/NaOH, has remarkably high solubility, approximately 3.9 M, and possesses a theoretical capacity of 105 Ah L^–1. This capacity is the greatest among all reported catholytes thus far. Half-cell experiments indicate that there is a high level of reversibility and stability, with minimal capacity degradation over time. In addition to three-electrode configuration, the efficacy of MnO₄^–/NaOH is evaluated in full-cell redox flow systems utilizing alizarin as anolyte. The AORFB shows an open circuit voltage of approximately 1.3 V, which is nearly 250 mV higher than the state-of-the-art ferrocyanide-based AORFBs. This resulted in an energy and power output that is approximately 20% higher. In addition, the system exhibits consistent performance with minimal decrease in capacity (0.1% per day) while achieving approximately 85% energy efficiency and 100% coulombic efficiency. The impact of the cutoff potential and plausible degradation mechanisms of the catholyte are also discussed.

However, the residual alkali on LLZTO surface limits its application with polyvinylidene difluoride (PVDF)-contained binders, and the uncontrollable lithium dendrites growing between the grain boundaries of LLZTO particles would lead to rapid capacity fading and potential short circuit risk.
