摘要

前封面重点介绍了一项研究，探讨了碳电极修饰和铋沉积如何影响KCrPDTA/K4Fe(CN)6液流电池的性能。在热活化电极上形成较大的铋沉积，由于氢的析出增强，降低了库仑效率，而较小的沉积则提高了整体效率。这些发现强调了控制催化剂形态对平衡功率输出和电池寿命的重要性。更多信息可以在D. Reber及其同事的研究文章中找到（DOI: 10.1002/bat .202400696）。

Cover Picture: Impact of Thermal Electrode Activation on Electrocatalyst Performance in KCrPDTA/K4Fe(CN)6 Flow Batteries (Batteries & Supercaps 3/2025)

The Front Cover highlights a study that explored how carbon electrode modifications and bismuth deposition affect performance in KCrPDTA/K₄Fe(CN)₆ flow batteries. Larger bismuth deposits that form on thermally activated electrodes reduce the Coulombic efficiency due to enhanced hydrogen evolution, whereas smaller deposits improve the overall efficiency. These findings highlight the importance of controlling catalyst morphology to balance power output and cell longevity. More information can be found in the Research Article by D. Reber and co-workers (DOI: 10.1002/batt.202400696).
