Abstract

Zinc-based flow batteries (ZFBs) are promising for large-scale energy storage applications. However, the formation of Zn dendrites and the limited areal capacity of ZFBs hinder their further development. In this study, we designed a digital light-processed 3D-printed pillar array pore ceramic membrane (3DPC) to construct ZFBs with high areal capacity and long cycle life. The pillar array pore design reduces the transmembrane resistance by ~60% and facilitates K⁺ and Na⁺ transport. The pore arrays serve as electrolyte reservoirs to regulate interfacial ion distribution and provide sufficient space for Zn deposition. Moreover, the surface hardness of the ceramics up to 1.46 GPa provides resistance against zinc dendrite damage. Furthermore, the cell based on the designed 3DPC exhibits a stable energy efficiency exceeding 79% during operation for over 950 h at an areal capacity of 280 mAh cm⁻². This study demonstrates the promising potential of 3D-printed ceramic membranes for metal-based flow batteries.

用于高面积容量锌基液流电池的3d打印柱阵孔陶瓷膜

锌基液流电池（ZFBs）在大规模储能应用中具有广阔的前景。然而，锌枝晶的形成和有限的面积容量阻碍了zfb的进一步发展。在这项研究中，我们设计了一种数字光处理3d打印柱阵列孔陶瓷膜（3DPC）来构建具有高面积容量和长循环寿命的zfb。柱阵孔设计可降低约60%的跨膜阻力，有利于K+和Na+的传输。孔阵列作为电解质储层，调节界面离子分布，为锌沉积提供充足的空间。此外，陶瓷的表面硬度高达1.46 GPa，具有抗锌枝晶损伤的能力。在面积容量为280 mAh cm−2的情况下，基于3DPC的电池在运行超过950 h时的稳定能量效率超过79%。这项研究展示了3d打印陶瓷膜用于金属基液流电池的巨大潜力。
