Abstract

Herein, we developed polyacrylonitrile (PAN)-based nanoporous composite membranes incorporating aluminum diethylphosphinate (ADEP) for use as a heat-resistant and flame-retardant separator in high-performance and safe lithium-ion batteries (LIBs). ADEP is phosphorus-rich, thermally stable, and flame retardant, and it can effectively suppress the combustibility of PAN nanofibers. Nanofibrous membranes were obtained by electrospinning, and the content of ADEP varied from 0 to 20 wt%. From the vertical burning test, it was demonstrated that the flame retardancy of the composite membranes was enhanced when more than 5 wt% of ADEP was added to PAN, potentially increasing the safety level of LIBs. Moreover, the composite membrane showed higher ionic conductivity and electrolyte uptake (0.83 mS/cm and 137%) compared to those of commercial polypropylene (PP) membranes (Celgard 2400: 0.65 mS/cm and 63%), resulting from interconnected pores and the polar chemical composition in the composite membranes. In terms of battery performance, the composite membrane showed highly stable electrochemical and heat-resistant properties, including superior discharge capacity when compared to Celgard 2400, indicating that the PAN/ADEP composite membrane has the potential to be used as a heat-resistant and flame-retardant separator for safe and high-power LIBs.

摘要

在此，我们开发了一种基于聚丙烯腈（PAN）的纳米多孔复合膜，其包含二乙基次膦酸铝（ADEP），用作高性能安全锂离子电池（LIBs）中的耐热且阻燃的隔膜。ADEP富含磷、热稳定且具有阻燃性，它能有效抑制PAN纳米纤维的可燃性。通过静电纺丝获得纳米纤维膜，ADEP的含量在0至20 wt%之间变化。垂直燃烧试验表明，当向PAN中添加超过5 wt%的ADEP时，复合膜的阻燃性增强，这可能会提高LIBs的安全水平。此外，与商用聚丙烯（PP）膜（Celgard 2400：0.65 mS/cm和63%）相比，复合膜表现出更高的离子电导率和电解质吸收率（0.83 mS/cm和137%），这是由于复合膜中相互连通的孔隙和极性化学组成所致。在电池性能方面，复合膜表现出高度稳定的电化学和耐热性能，包括与Celgard 2400相比具有优异的放电容量，这表明PAN/ADEP复合膜有潜力用作安全高功率LIBs的耐热且阻燃的隔膜。
