Although lithium-ion batteries have already had a considerable impact on making our lives smarter, healthier, and cleaner by powering smartphones, wearable devices, and electric vehicles, demands for significant improvement in battery performance have grown with the continuous development of electronic devices. Developing novel anode materials offers one of the most promising routes to meet these demands and to resolve issues present in existing graphite anodes, such as a low theoretical capacity and poor rate capabilities. Significant improvements over current commercial batteries have been identified using the electrospinning process, owing to a simple processing technique and a wide variety of electrospinnable materials. It is important to understand previous work on nanofiber anode materials to establish strategies that encourage the implementation of current technological developments into commercial lithium-ion battery production, and to advance the design of novel nanofiber anode materials that will be used in the next-generation of batteries. This review identifies previous research into electrospun nanofiber anode materials based on the type of electrochemical reactions present and provides insights that can be used to improve conventional lithium-ion battery performances and to pioneer novel manufacturing routes that can successfully produce the next generation of batteries.
尽管锂离子电池通过为智能手机、可穿戴设备和电动汽车供电，已经对使我们的生活更智能、更健康、更清洁产生了相当大的影响，但随着电子设备的不断发展，对电池性能大幅提升的需求也在增加。开发新型负极材料是满足这些需求以及解决现有石墨负极存在的问题（如理论容量低和倍率性能差）的最有前景的途径之一。由于电纺丝工艺具有简单的加工技术和多种可电纺材料，已证实使用该工艺可使电池性能比目前的商用电池有显著提升。了解以往关于纳米纤维负极材料的研究工作，对于制定鼓励将当前技术发展应用于商用锂离子电池生产的策略，以及推进将用于下一代电池的新型纳米纤维负极材料的设计至关重要。本综述根据所涉及的电化学反应类型，对以往关于电纺纳米纤维负极材料的研究进行了总结，并提供了相关见解，可用于改善传统锂离子电池的性能，以及开拓能够成功生产下一代电池的新型制造路线。
