Nanofibers (NFs) and composite NFs have been widely used as electrode and separator materials in lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) due to their high surface-area-to-volume ratio and versatility of their morphologies. The majority of carbon-fibers (CFs) anodes have been prepared by electrospinning and subsequent thermal treatment. Nevertheless, the low fiber yield and safety hazards associated with this method have raised concerns and limited the commercialization of composite CF anodes. Fiber and nanofiber processing methods such as centrifugal spinning can overcome low productivity and eliminate the use of a high voltage to produce fibers. In the present work, centrifugally spun fibers with alloying, transition metal oxides, and transition metal sulfite-based materials are presented and discussed for potential use as anode materials in LIBs and SIBs. Emphasis is given on the centrifugal spinning process and its effects on fiber formation, morphology, and structure of these nanocomposite anodes.

离心纺复合纤维的最新进展及其作为锂离子和钠离子电池负极材料的性能

纳米纤维(NFs)和复合纤维NFs因其高的表面积体积比和其形貌的多样性而被广泛用作锂离子电池(LIB)和钠离子电池(SIB)的电极和隔板材料。大多数碳纤维(CFs)阳极是通过静电纺丝和随后的热处理制备的。然而,与这种方法相关的低纤维产率和安全隐患引起了人们的关注,并限制了复合CF阳极的商业化。诸如离心纺丝之类的纤维和纳米纤维加工方法可以克服低生产率,并且消除了使用高压生产纤维的麻烦。在目前的工作中,离心纺成纤维与合金化的过渡金属氧化物,本文介绍和讨论了基于亚硫酸盐过渡金属的材料,并有可能用作LIB和SIB中的阳极材料。重点介绍了离心纺丝工艺及其对这些纳米复合阳极纤维形成,形态和结构的影响。
