The applications of HEA nanomaterials in electrocatalysis open prospective new avenues for catalyst discovery and performance optimization.

An in-depth comprehension of the structure-performance relationship of HEA electrocatalysts is urgently needed to advance their reasonable development further. In this review, design methodologies of HEA nanomaterials are first discussed from four aspects, i.e., the composition, size, shape, and crystal structure, with the ultimate goal of achieving optimal catalytic activity, selectivity, and stability. Subsequently, recent progress in diverse electrochemical reactions, including hydrogen evolution, hydrogen oxidation, oxygen evolution, oxygen reduction, carbon dioxide reduction, alcohol oxidation and nitrate reduction, is summarized with a focus on the design principles of HEA catalysts toward specific reactions.

These batteries aim to address the weight and volume efficiency challenges faced by conventional batteries, particularly in electric vehicles, thereby extending driving range. As a crucial component of structural batteries, the electrolyte must not only facilitate ion transport but also provide mechanical integrity under flexural loads or impacts. However, developing a structurally strong electrolyte is a significant challenge, as high mechanical strength often leads to reduced ionic conductivity. Therefore, the full potential of structural batteries can only be realized once suitable multifunctional structural electrolytes are developed. This review examines the state-of-the-art in structural electrolytes, focusing on thermoplastic and thermoset polymer-based electrolytes for structural batteries. It explores the underlying ion transport mechanisms and mechanical enhancement strategies. The review also discusses how electrolyte composition—such as the choice of polymer matrix, inorganic fillers, solvents, and ionic liquid additives—affects both mechanical and electrochemical properties, as well as the role of interfacial stability. Furthermore, block copolymer electrolytes and molecular ion composite solid electrolytes based on rigid-rod polymers are proposed as promising candidates for structural electrolytes.

It holds immense promise and application potential in facilitating the transition towards sustainable energy solutions. Nevertheless, the widespread commercial adoption of PEMFCs is hindered by the immaturity of individual components within the system. Chief among these obstacles are the high cost and inadequate activity of the cathode catalyst, limited proton conductivity of the PEM, and fuel starvation issues at the anode. Furthermore, concerns regarding the mass transport limitation and the degradation of the membrane electrode assembly (MEA) during practical operation collectively impede performance optimization and lifetime extension. Despite the advancements in delicate catalyst design, the complex synthesis processes coupled with trial-and-error methodologies complicate scalability for large-scale applications. In response to these multifaceted challenges, incorporating functional additives (FAs) has emerged as a promising and versatile strategy. These smart additives, with diverse and unique functions, have rapidly gained traction and are being applied across nearly all components of the MEA. However, research efforts to utilize FAs to achieve high-performance and durable PEMFCs are not comprehensively documented, particularly concerning the underlying operational mechanisms. This review aims to bridge this knowledge gap by consolidating current understanding, providing a detailed analysis of the diverse mechanisms at play, and highlighting both the merits and limitations associated with the FA strategy.
