| contents | Purified molybdenite encapsulated in N-doped carbon nanofibers as binder-free anodes for flexible lithium-ion hybrid capacitors. Li, Lingyao Zhou, Zhixuan Xu, Fang Zhao, Yuan Chen, Tao Gao, Jie Zhang, Yifu Liang, Tian Li, Yuzhu Zhu, Xiaoming Molybdenite possesses high natural abundance and a high theoretical lithium storage capacity but is limited by its low intrinsic conductivity and volume expansion during cycling. Herein, a flexible and binder-free anode is designed by encapsulating purified molybdenite nanosheets within nitrogen-doped carbon nanofibers (MoS@CNF) a scalable electrospinning and carbonization process. The unique "necklace-like" structure, in which MoS nanosheets are uniformly embedded within interconnected conductive CNFs, not only exposes abundant active sites but also enhances both the electrical conductivity and mechanical stability. The delicate nanostructure of MoS@CNF facilitates rapid ion/electron transport and alleviates the volume stress of MoS during electrochemical processes, consequently contributing to its outstanding rate capability (544.0 mAh g at 2 A g) and excellent cycling performance (716.9 mAh g after 500 cycles at 1 A g). The MoS@CNF anode is further coupled with a flexible cathode (activated carbon cast onto CNF) to construct a lithium-ion hybrid capacitor, which exhibits a high energy and power density (84.3 Wh kg at 10 kW kg) while demonstrating negligible capacity decay even under harsh bending conditions. This work provides a cost-effective strategy for transforming natural ore into high-performance electrodes for flexible energy storage. |
