The development of new, large-scale stationary energy storage technologies, such as redox flow batteries, is vital to fully utilise renewable energy resources. However, test cells capable of assisting in this development can be prohibitively expensive and unreliable. Here, an open-source, low-cost, customisable 3D-printed test cell is presented as an alternative. These newly developed cells are designed to be printable using affordable desktop 3D-printers and readily available polymers. A simulation-led design optimisation yielded an improved internal manifold geometry that demonstrated improved real-world performance. The polymers used have been tested for chemical compatibility and through the use of advanced X-ray micro-CT, optimised parameters for 3D-printing have been identified. This framework provides a straightforward process enabling researchers to produce robust cells at an extremely low cost, helping to democratise research and widen accessibility to flow electrochemistry.

本篇论文的补充文件介绍了一种开源的3D打印红ox流电池测试单元平台。新型大规模固定式储能技术，如红ox流电池的发展，对于充分利用可再生能源资源至关重要。然而，辅助这一发展的测试单元往往成本高昂且可靠性不足。在此，我们提出了一种开源、低成本、可定制的3D打印测试单元作为替代方案。这些新开发的单元旨在利用经济实惠的桌面3D打印机和 readily available polymers进行打印。通过仿真引导的设计优化，实现了内部流道几何形状的改进，从而在现实世界中展现了更优的性能。所使用的聚合物已经过化学兼容性测试，并通过先进的X射线显微CT技术，确定了3D打印的优化参数。这一框架提供了一个简便的过程，使研究人员能够以极低的成本生产出坚固的单元，从而有助于推动研究民主化，拓宽流动电化学领域的可及性。
