Maintaining structural stability and alleviating the intrinsic poor conductivity of cathode materials are of great importance for practical application of Li–S batteries. Introducing void space and a highly conductive host to accommodate the volume changes and enhance the conductivity would be a smart design to achieve robust construction; effective electron and ion transportation, thus, lead to prolonged cycling life and excellent rate performance. In this regard, we report the design of carbonaceous hybrid with vertically aligned graphene assembled on multi-yolk/shell structured [email protected] nanofibers to afford synergistic properties of enough space, strong chemisorption and active electrocatalysis, high electrical conductivity as a sulfur host. Thus, the as-prepared sulfur cathode delivers an excellent cyclability over 800 cycles, a high areal capacity of 6.81 mA h cm² at a high sulfur loading (10.5 mg). More importantly, soft package battery was also prepared with a capacity of 530 mAh g^-1 and 46.5 mAh in the first cycle at a sulfur loading of 4.5 mg cm^-2, which reveals its potential in promoting the practical application of Li–S batteries.

维持结构稳定性并减轻阴极材料固有的导电性差对于锂锂电池的实际应用非常重要。引入空隙空间和高导电性主体以适应体积变化并提高导电性将是实现坚固结构的明智设计；有效的电子和离子传输，从而延长了循环寿命并提高了倍率性能。在这方面，我们报告了在多卵黄/壳结构的[电子邮件保护]纳米纤维上组装垂直排列的石墨烯的碳质杂化物的设计，以提供足够的空间协同作用，强大的化学吸附和活性电催化作用，高电导率作为硫主体。因此，所制备的硫阴极在​​800个循环中具有出色的循环能力，²在高硫负荷下（10.5 mg）。更重要的是，在第一个循环中，在硫负荷为4.5 mg cm ^{-2的情况下}，还准备了软包装电池，容量为530 mAh g ^-1和46.5 mAh ，这显示出其在促进Li–S电池实际应用中的潜力。
