Construction of Carbon Nanofiber-Wrapped SnO₂ Hollow Nanospheres as Flexible Integrated Anode for Half/Full Li-Ion Batteries.

ABSTRACT: 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 produ
