The growing demand for clean, decentralized energy has increased interest in blue energy, which generates power from water with different salt concentrations. Despite its potential as a renewable, low-cost energy source, optimizing electrode materials remains a challenge. This work presents a nanomaterial developed via microwave-assisted sol-gel methodology for blue energy applications, where ion diffusion and charge storage are critical. AX-7 carbon, designed for this study, features wide pores, enhancing ion diffusion. Compared to commercial NORIT carbon, AX-7 has a higher mesopore volume and external surface area, improving its overall performance. The synthesis process has been optimized and scaled up for evaluation in CAPMIX electrochemical cell stacks. Moreover, the lower series resistance (Rs) significantly boosts energy recovery, with AX-7 demonstrating superior performance. This advantage is especially evident during fresh-water cycles, where this material achieves significantly lower Rs compared to the commercial one.
对清洁、分散能源日益增长的需求，使得人们对蓝能源的兴趣增加，蓝能源利用不同盐浓度的水来发电。尽管其作为可再生、低成本能源具有潜力，但优化电极材料仍然是一项挑战。这项工作展示了一种通过微波辅助溶胶 - 凝胶法开发的用于蓝能源应用的纳米材料，在蓝能源应用中离子扩散和电荷存储至关重要。为本研究设计的AX - 7碳具有宽孔，可增强离子扩散。与商用诺芮特碳相比，AX - 7具有更高的中孔体积和外表面积，从而改善了其整体性能。合成工艺已得到优化并扩大规模，以便在CAPMIX电化学电池堆中进行评估。此外，较低的串联电阻（Rs）显著提高了能量回收，AX - 7表现出卓越的性能。这一优势在淡水循环期间尤为明显，在此期间该材料与商用材料相比实现了显著更低的Rs。
