摘要

由于原材料和工艺的限制,商用锂离子电池(LIB)中使用的聚烯烃隔膜已逐渐无法满足高端电池在能量密度、功率密度和安全性方面不断提高的要求。因此,为包括锂离子电池和锂-S 电池在内的先进锂(Li)基可充电电池开发下一代隔膜非常重要。通过电纺丝技术制造的无纺纳米纤维膜具有工艺简单、设备成本低、微孔结构可控、材料适用性广、功能多样等优点,是极具吸引力的高端隔膜候选材料。本综述从设备、工艺和环境以及聚合物溶液系统等方面对用于分离器的电纺丝技术进行了综述。此外,还从纳米纤维和隔膜的成分和结构方面介绍了在先进锂离子电池和锂-S 电池中改进电纺隔膜的策略。最后,提出了电纺隔膜在学术界和工业界面临的挑战和前景。我们希望这些系统性的讨论能够为电纺隔膜的商业应用提供信息,并为先进锂电池功能性电纺隔膜的设计提供新的视角。

A review of electrospun separators for lithium-based batteries: Progress and application prospects

Due to the limitations of the raw materials and processes involved, polyolefin separators used in commercial lithium-ion batteries (LIBs) have gradually failed to meet the increasing requirements of high-end batteries in terms of energy density, power density, and safety. Hence, it is very important to develop next-generation separators for advanced lithium (Li)-based rechargeable batteries including LIBs and Li–S batteries. Nonwoven nanofiber membranes fabricated via electrospinning technology are highly attractive candidates for high-end separators due to their simple processes, low-cost equipment, controllable microporous structure, wide material applicability, and availability of multiple functions. In this review, the electrospinning technologies for separators are reviewed in terms of devices, process and environment, and polymer solution systems. Furthermore, strategies toward the improvement of electrospun separators in advanced LIBs and Li–S batteries are presented in terms of the compositions and the structure of nanofibers and separators. Finally, the challenges and prospects of electrospun separators in both academia and industry are proposed. We anticipate that these systematic discussions can provide information in terms of commercial applications of electrospun separators and offer new perspectives for the design of functional electrospun separators for advanced Li-based batteries.
