A three-dimensional (3D) flexible hybrid foam composed of graphene [email protected] nanotubes decorated with MoS₂ nanoparticles is synthesized for flexible anode applications in lithium-ion battery. The inner layer of graphene foam (GF), serving as a 3D skeleton of the hybrid foam, enlarges the electrode/electrolyte contact, shortens the diffusion distance of Li⁺ ions and provides enough internal void space to accommodate the large volume change of MoS₂ nanoparticles. The middle carbon nanotubes (CNT) layer wrapped on the graphene foam is more conductive to facilitate electron/ion transport within the hybrid foam and can further enhance the flexibility of the hybrid foam. The outer layer of active MoS₂ nanoparticles can provide high specific capacity. Owing to these advantages, the flexible [email protected]@MoS₂ electrodes delivers a specific capacity of 935 mAh g⁻¹ at a current density of 0.1 A g⁻¹, high reversible capacity of 606 mAh g⁻¹ after 200 cycles at 0.2 A g⁻¹.

合成了由装饰有MoS ₂纳米粒子的石墨烯（受电子邮件保护的）纳米管组成的三维（3D）柔性杂化泡沫，用于锂离子电池中的柔性阳极应用。石墨烯泡沫（GF）的内层用作混合泡沫的3D骨架，可扩大电极/电解质的接触，缩短Li ⁺离子的扩散距离，并提供足够的内部空隙空间以适应MoS ₂的大体积变化纳米粒子。包裹在石墨烯泡沫上的中间碳纳米管（CNT）层更具导电性，以促进杂化泡沫内的电子/离子传输，并可以进一步增强杂化泡沫的柔韧性。活性MoS ₂的外层纳米粒子可以提供高比容量。由于这些优点，灵活的[电子邮件保护] @MoS ₂电极在0.1 A g ^-1的电流密度下可提供935 mAh g ^-1的比容量，在0.2的200次循环后具有606 mAh g ^-1的高可逆容量A g ^-1。
