摘要

封面展示了聚乙烯隔膜孔隙率对锂离子电池电化学性能的影响。研究结果表明，隔膜的固有特性（如电阻和孔隙率）在决定动力性能方面起着至关重要的作用，尤其是在使用厚电极的电池中。这项研究强调了根据特定电极设计优化隔膜特性的必要性。更多信息，请参阅 H. Lee、Y. M. Lee 及合作者的研究文章（DOI.Lee 及合作者的研究文章中（DOI: 10.1002/batt.202400638）。

Cover Picture: Optimizing the Power Performance of Lithium-Ion Batteries: The Role of Separator Porosity and Electrode Mass Loading (Batteries & Supercaps 4/2025)

The Front Cover illustrates the impact of polyethylene separator porosity on the electrochemical performance of lithium-ion batteries. The findings demonstrate that intrinsic separator properties, such as resistance and porosity, play a critical role in determining power performance, particularly in cells with thick electrodes. This study highlights the necessity of optimizing separator characteristics to align with specific electrode designs. More information can be found in the Research Article by H. Lee, Y. M. Lee and co-workers (DOI: 10.1002/batt.202400638).
