Bioinspired energy materials, which replicate nature's optimized systems, have great potential to create a platform for solar energy harvesting breakthroughs, energy storage, and catalytic conversion. This review offers a synthesis of the latest developments in biomimetic photovoltaics, battery technologies, and catalytic systems, including their benefits, limitations, and prospects for commercialization. Moth-eye-inspired nanostructures in solar cells have realized 20%–40% enhancements in light absorption over planar surfaces. Bioinspired battery electrodes, with hierarchical porous architectures imitated from wood and coral structures, demonstrate up to 30% enhancement in ion transport and cycle life. Enzyme-mimetic catalysts, especially Ni–Fe hydrogenase analogues, provide hydrogen evolution efficiencies of more than 85%, on par with platinum-based systems but at below 10% of the cost. This review also covers frontier topics like biomimetic thermoelectrics and triboelectric nanogenerators, which have shown up to 30% increased energy conversion efficiency based on nature-mimicking nanostructuring. The uniqueness of this research is that it performs integrative analysis across various energy platforms based on comparative performance, lifecycle assessment, and technological readiness levels. It points to major research lacunas in scaling, stability, and material integration, and suggests routes to fill the laboratory discoveries–industry implementation gap. The originality of this review is in its cross-domain integration, comparative data synthesis, and sustainability-focused analysis of bioinspired energy materials. This review intends to be a go-to resource for understanding sustainable energy technology evolution through bioinspiration.</p>\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145686281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, PCMs are hindered by their low thermal conductivity and integration challenges. In this research, a novel double-fin counterflow SAH was developed using polygonal galvanized iron absorber panels and transverse rectangular fins. The fins were integrated with a phase-change material composed of paraffin wax and iron filings (2 L of paraffin and 50 g of iron filings). Experiments were conducted in Hawija city, Iraq (35.4586°N, 43.8319°E), over 6 consecutive clear days, evaluating setups with and without PCMs under actual environmental conditions. Key parameters, including efficiency, output temperature, and heat gain, were assessed. The results showed that the inclusion of PCM increased the daily thermal efficiency by 15.2% (from 31.04% to 35.75%), extended heat delivery by 5 h after sunset (until 8:00 p.m. compared to 5:00 p.m. without PCM), and reduced the peak outlet temperature by 7.3% (32.9°C vs. 35.5°C at noon). Furthermore, the average daytime temperature was elevated by 28.8% (18.3°C vs. 14.2°C). This study presents an economical solution for solar thermal stabilization, specifically designed for agricultural drying and building heating in sunny regions.

The research problem stems from the need to improve heat absorption and increase the efficiency of solar energy conversion, given the environmental challenges and high costs of conventional energy. The study was carried out practically through the manufacture and installation of a pneumatic solar collector on the roof of the building of the Renewable Energies Research Unit at the Hawija Technical Institute, where the performance of the two systems was measured using precision instruments. The results showed that the metal fibers absorbed more heat during peak periods; the power gain reached 200 W compared to 190 W when using glass balls, but they lost heat quickly after that. In contrast, glass spheres retained heat for longer periods, resulting in a higher thermal efficiency of 57% compared to 52% for metal fibers. These results indicate that the performance of the solar collector was better when using glass balls due to their ability to store heat for longer periods and reduce energy loss, making them a more efficient and sustainable option in solar heating and ventilation systems. The novelty of this study lies in its direct experimental comparison between two distinct types of porous media—glass balls and metal fibers—under identical conditions, which has not been previously explored in the literature.

This study establishes a novel aluminum–carbon solid-state battery system featuring three synergistically engineered components: a plasma-sprayed Al–Si–Mg–Zn alloy anode modified by phosphoric acid, a porous magnesium silicate-based solid electrolyte, and a sodium-enriched graphite cathode. The aluminum anode, treated with phosphoric acid and annealed at 300°C, forms a partially crystalline AlPO<sub>4</sub> layer that enhances interfacial stability and ion transport, resulting in a specific capacity of 901 mAh g<sup>−1</sup>—over 2.5 times higher than the untreated aluminum electrode. Similarly, the porous PB electrolyte, fabricated via PVA-assisted casting, demonstrated superior cycle life (> 100 cycles) compared to the dense compressed Ingot-B electrolyte (13 cycles), attributable to improved ion diffusion pathways and mechanical compliance. The sodium phosphate-modified graphite cathode further increased interlayer spacing and facilitated reversible Al<sup>3+</sup> storage, leading to markedly enhanced capacity and durability. The optimized full-cell configuration (S-Al10SiMgZ(P)/PB/GFN) delivered an initial specific capacity of 6278 mAh g<sup>−1</sup> and retained ~200 mAh g<sup>−1</sup> after 40 cycles, with a total cycle life exceeding 100 cycles.

X-ray diffraction (XRD) data reveal the greater crystallite size of NiP2 which further leads to higher surface area. Scanning electron microscopy (SEM) analysis shows that NiP2 is more porous due to well assembled morphology of NiS<sub>2</sub> nanosheets over PANI nanofibers. Among the nanocomposites, the NiP2 variant demonstrates superior electrochemical performance, achieving a specific capacitance of 217.88 F g<sup>−1</sup> at a current density of 1 A g<sup>−1</sup> in a 2 M KOH electrolyte. Further, enhancing the energy density of supercapacitors for advanced applications, the structure-modulated NiP2 (positive potential electrode) is integrated with functionalized carbon nanotubes (f-CNT) as the negative potential material, extending the voltage window from 0.65 to 1.4 V.

Unlike previous studies that focused on single or binary filler systems, this work introduces a novel multicomponent composite phase change material (CPCM) by incorporating varying loadings of expanded graphite (EG), hexagonal boron nitride nanosheets (h-BNNSs), MXene (Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>), and epoxy resin (ER) into the matrix of paraffin wax/polyethylene glycol/lauric acid to synergistically enhance thermal performance.
