摘要：
Natural sepiolite mineral has been commonly used in the industry because of its unique structure and physical properties. In this paper, we fabricated sepiolite-based battery separators by simple and inexpensive electrospinning technology. The as-prepared sepiolite-based separators show high thermal stability and excellent electrochemical properties, making them a superior candidate for long-term operation under thermally stressful conditions. Our research indicates that sepiolite can be employed to improve the reliability and electrochemical performance of polymer-based separators.
