Summary: In this study, three types of flexible 3D-interconnected carbon nanofibers were prepared and used as substrates for vertically grown ultrathin MoSe2 nanosheets. The resulting composites were employed as freestanding anodes for lithium-ion batteries, with the hollow multi-nanochannel structure of NHMCFs delivering the highest capacity after 400 cycles at 1 A g-1. The multi-nanochannel structure in NMCFs and NHMCFs helps alleviate volume changes during charge-discharge processes, while the uniform coating of MoSe2 nanosheets on NHMCFs increases mass loading and capacity.

Summary: Compared to conventional lithium batteries, lithium-sulfur (Li-S) batteries are low-cost, environmentally friendly, and have a high theoretical energy density. However, their commercialization is hindered by the insulating nature of sulfur materials and poor cycle stability. In this study, porous carbon nanofibers (PCNFs) were used as a cathode for Li-S batteries, effectively inhibiting the migration of soluble polysulfides. The PCNFs/S cathode exhibited excellent cycling stability, with an initial specific capacity of 835 mAh g(-1) at 0.1C and a reversible capacity of 98.6% after 100 cycles. This outstanding performance is attributed to the rational design of the electrode structure, which increases interfacial contact and provides a large number of electrochemically active sites for polysulfide storage.

Summary: In this work, nano Sn-SnOx embedded in multichannel hollow carbon nanofibers (Sn-SnOx@MCNF) were found to improve the lithium storage property of tin-based oxides. Sn-SnOx@MCNF exhibited quick ion transfer rate, enough catalytic active sites, high structure stability, little agglomeration, and superior buffering volume change during alloying/dealloying processes. The SnSnOx@MCNF-based electrodes demonstrated predominant reversibility, large capacity, and excellent rate capability during the lithium intercalation process. In practical applications, SnSnOx@MCNF-based electrodes showed a high reversible capacity of 669.2 mAh g-1 even after 600 cycles at 1.0 A g-1 and a high-rate capacity of 525.1 mAh g-1 at 4.0 A g-1. Sn-SnOx@MCNF could be a potential anode material for Li-ion batteries with superior Li-storage performance. Furthermore, a detailed synergistic enhancement mechanism between MCNF and nano Sn-SnOx was proposed.
