“…For instance, it has been proposed SnO 2 materials be synthesized at the nanoscale to effectively minimize volume-change stress and shorten the migration distance of Li + . Thus, considerable effort has been invested in the synthesis of nanoscale SnO 2 with various morphologies, such as nanoparticles [13,14], nanotubes [15,16], nanorods [17,18], porous structures [19,20], and hollow structures [21][22][23]. For these special structures, an efficient approach is to construct electrode materials with hollow nanostructures, which provide sufficient space to cushion the large volume variation and inhibit the excessive growth of an unstable solid electrolyte interphase (SEI) [24].…”

SnO2 is deemed a potential candidate for high energy density (1494 mAh g−1) anode materials for Li-ion batteries (LIBs). However, its severe volume variation and low intrinsic electrical conductivity result in poor long-term stability and reversibility, limiting the further development of such materials. Therefore, we propose a novel strategy, that is, to prepare SnO2 hollow nanospheres (SnO2-HNPs) by a template method, and then introduce these SnO2-HNPs into one-dimensional (1D) carbon nanofibers (CNFs) uniformly via electrospinning technology. Such a sugar gourd-like construction effectively addresses the limitations of traditional SnO2 during the charging and discharging processes of LIBs. As a result, the optimized product (denoted SnO2-HNP/CNF), a binder-free integrated electrode for half and full LIBs, displays superior electrochemical performance as an anode material, including high reversible capacity (~735.1 mAh g−1 for half LIBs and ~455.3 mAh g−1 at 0.1 A g−1 for full LIBs) and favorable long-term cycling stability. This work confirms that sugar gourd-like SnO2-HNP/CNF flexible integrated electrodes prepared with this novel strategy can effectively improve battery performance, providing infinite possibilities for the design and development of flexible wearable battery equipment.
