N2 - The increasing global demand for efficient, durable, and cost-effective energy storage solutions presents a significant challenge, particularly in the context of sustainable energy systems. A critical problem in this domain is the need for electrode materials that can deliver high performance while being scalable for industrial applications. This review addresses this challenge by focusing on the recent advancements in hexacyanoferrate-based materials, specifically for supercapacitor (SC) applications. Hexacyanoferrates (HCFs), including Prussian Blue (PB) and its analogs, are recognized for their distinctive three-dimensional frameworks and favorable redox properties, making them promising candidates for electrochemical energy storage. We provide a comprehensive analysis of the latest research on the synthesis, structural modifications, and electrochemical performance of HCF materials, emphasizing their role in enhancing specific capacitance, specific energy, and cyclic durability. Key advancements, such as the development of transition metal HCFs and their derivatives, are highlighted for their superior electrochemical properties. Additionally, we examine the integration of HCFs with polymers, conducting polymers, and carbon-based materials to create composites that further improve supercapacitor performance. The review also critically evaluates the challenges associated with scaling up HCF-based SCs from laboratory research to commercial manufacturing. By synthesizing current knowledge and identifying gaps in the existing research, this review proposes future directions aimed at overcoming these challenges. Ultimately, this comprehensive overview underscores the potential of HCF-based SCs to contribute significantly to the advancement of sustainable energy storage technologies.
