Supercapacitors (SCs) with the advantages of high power density, fast charge/discharge and no memory effect have been regarded as potential energy storage devices. Mo-based materials have been extensive used as active electrode materials in pseudocapacitors due to their high theoretical specific capacities, eminent electrochemical activities, as well as highly reversible redox reactions. However, the serious self-aggregation and huge volume change of Mo-based materials can cause a dramatic capacity decay during the electrochemical process. Carbon nanofibers (CNFs) synthesized through electrospinning technology are endowed with excellent mechanical strength and satisfactory electrical conductivity, which are regarded as an ideal matrix for composite materials. Hitherto, Mo-based materials incorporated with CNFs through electrospinning technology have arisen intensive attraction in SCs. The electrospinning strategy can realize evenly dispersed Mo-based materials in CNFs. The as-prepared Mo-based nanocomposite fibers with good flexibility and brilliant chemical properties can validly avoid the self-aggregation and enhance the electrochemical performance. In this review, the basic process and principle of the electrospinning technique, strategies to prepare CNFs with special structure, and various Mo-based nanocomposite fibers are introduced. In addition, the application of the Mo-based nanocomposite fibers in SCs, as well as the current situation and challenges of Mo-based nanocomposite fibers are also summarized.

电纺钼基纳米复合纤维作为超级电容器负极材料的研究进展

超级电容器(SCs)具有高功率密度、快速充放电和无记忆效应等优点,被视为潜在的储能装置。钼基材料由于其高理论比容量、卓越的电化学活性以及高度可逆的氧化还原反应,已被广泛用作赝电容器中的活性电极材料。然而,Mo基材料严重的自聚集和巨大的体积变化会导致电化学过程中的容量急剧下降。通过静电纺丝技术合成的碳纳米纤维(CNFs)具有优异的机械强度和良好的导电性,被认为是复合材料的理想基体。迄今为止,通过静电纺丝技术与 CNF 结合的 Mo 基材料在 SCs 中引起了强烈的吸引力。静电纺丝策略可以在 CNF 中实现均匀分散的 Mo 基材料。所制备的钼基纳米复合纤维具有良好的柔韧性和优异的化学性能,可有效避免自聚集并提高电化学性能。在这篇综述中,介绍了静电纺丝技术的基本过程和原理、制备具有特殊结构的 CNFs 的策略以及各种 Mo 基纳米复合纤维。此外,还总结了钼基纳米复合纤维在SCs中的应用,以及钼基纳米复合纤维的现状和挑战。静电纺丝策略可以在 CNF 中实现均匀分散的 Mo 基材料。所制备的钼基纳米复合纤维具有良好的柔韧性和优异的化学性能,可有效避免自聚集并提高电化学性能。在这篇综述中,介绍了静电纺丝技术的基本过程和原理、制备具有特殊结构的 CNFs 的策略以及各种 Mo 基纳米复合纤维。此外,还总结了钼基纳米复合纤维在SCs中的应用,以及钼基纳米复合纤维的现状和挑战。静电纺丝策略可以在 CNF 中实现均匀分散的 Mo 基材料。所制备的钼基纳米复合纤维具有良好的柔韧性和优异的化学性能,可有效避免自聚集并提高电化学性能。在这篇综述中,介绍了静电纺丝技术的基本过程和原理、制备具有特殊结构的 CNFs 的策略以及各种 Mo 基纳米复合纤维。此外,还总结了钼基纳米复合纤维在SCs中的应用,以及钼基纳米复合纤维的现状和挑战。在这篇综述中,介绍了静电纺丝技术的基本过程和原理、制备具有特殊结构的 CNFs 的策略以及各种 Mo 基纳米复合纤维。此外,还总结了钼基纳米复合纤维在SCs中的应用,以及钼基纳米复合纤维的现状和挑战。在这篇综述中,介绍了静电纺丝技术的基本过程和原理、制备具有特殊结构的 CNFs 的策略以及各种 Mo 基纳米复合纤维。此外,还总结了钼基纳米复合纤维在SCs中的应用,以及钼基纳米复合纤维的现状和挑战。
