Abstract

The increasing global energy demand and environmental issues caused by fossil fuels necessitate renewable energy systems and effective storage solutions. This study explores the design of energy storage electrodes using 3D printing with a 316L stainless steel and polymer filament via fused deposition modeling. High-temperature sintering was used to debind the polymer and consolidate the stainless steel particles, with ceramic coatings (carbon and SiC) applied to prevent oxidation during heating. Electrodes sintered under carbon exhibited significantly higher specific capacitance (775 mF cm⁻² at 10 mV s⁻¹) compared to those sintered under SiC (< 1 mF cm⁻²). Varying the infill ratio (40%, 70%, and 100%) revealed that a 70% infill provided optimal surface morphology and areal capacitance. This work is significant as it demonstrates a novel approach to utilizing 3D printing technology for the fabrication of customizable and efficient electrodes, addressing the critical need for energy storage applications.

3d打印不锈钢电极的储能性能：烧结覆盖和填充密度变化的影响

日益增长的全球能源需求和由化石燃料引起的环境问题需要可再生能源系统和有效的存储解决方案。本研究利用316L不锈钢和聚合物长丝，通过熔融沉积建模，探索3D打印储能电极的设计。高温烧结用于脱粘聚合物和巩固不锈钢颗粒，并使用陶瓷涂层（碳和碳化硅）来防止加热过程中的氧化。在碳下烧结的电极比电容（10 mV s−1时775 mF cm−2）明显高于在SiC下烧结的电极（1 mF cm−2）。不同的填充比例（40%、70%和100%）表明，70%的填充可以提供最佳的表面形貌和面电容。这项工作意义重大，因为它展示了一种利用3D打印技术制造可定制和高效电极的新方法，解决了储能应用的关键需求。图形抽象
