Many EFR technologies utilize cation-exchange membranes (CEMs) extensively due to their high conductivity and chemical stability; however, CEMs do not obstruct cationic active species and cause unwanted electrolyte cross-contamination in EFR technologies that use cations as active species, e.g., redox flow batteries (RFBs) and electrodialysis. Anion-exchange membranes (AEMs) innately block cations; however, they are not sufficiently durable. Developing strategies to enhance their durability is necessary to expand their application in RFBs and similar EFRs. This work investigates the morphology control of immiscible polymer-blended AEMs via tuning the blend composition and casting temperature. Marangoni-Bénard effect was identified as the dominant mechanism behind the perturbations in the casting solution film. Marangoni cells appear at AEMs cast at &gt;40 °C, leading to desirable lateral phase separation of polymers. The ionic conductivity of lateral phase-separated AEMs improved with lowering the casting temperature, indicating that excessively heightened perturbations in the casting films damage the conductivity routes. Adding 20% PVDF-<i>co</i>-HFP to the AEM reduced the water uptake (30 vs 58%), hence increasing the durability of the AEM (conductivity loss of 21 vs 63% over a week) while sacrificing minimal ionic conductivity (11 vs 13 mS·cm^–1).

This review stands out by comprehensively analyzing various GCN synthesis methods such as hydrothermal, solvothermal, and sol–gel techniques and critically examining how these methods influence electrochemical performance. A particular focus is placed on identifying optimal synthesis techniques through a detailed comparison of their impact on key functional parameters. This review differentiates from previous studies’ in-depth exploration of advanced strategies to enhance GCN’s electrochemical properties.

These cutting-edge strategies have not been systematically explored in other reviews, positioning this article as a forward-thinking contribution to the field. In addition, the review takes a broader, interdisciplinary approach by examining GCN’s functionality in other applications, such as water splitting, and identifying critical commonalities between the functional parameters of these applications and those of supercapacitors. This cross-application analysis, rarely addressed in previous literature, opens new avenues for GCN development, suggesting that insights from related fields can accelerate the optimization of GCN as a supercapacitor electrode.
