Homogeneous encapsulation of Si/SnO 2 nanospheres in tunable carbon electrospinning nanofibers for high-performance lithium-ion battery

As a result of silicon's abundant deposits and high theoretical capacity, substantial research has been conducted into its potential as a lithium-ion battery anode material. Academic research in silicon-based materials focuses on improving the silicon's inferior conductivity and decreasing its bulk solid impact. In the current study, anodes consisting of Si/SnO 2 @Carbon Nanofibers (CNFs) with dual modification were manufactured by electrostatic spinning. It has an outstanding reversible specific capacity at high current densities of 1 A g −1. Furthermore, after 1000 cycles in lithium-ion batteries, the exact capacity of 931.2 mAh g −1 is stable. Moreover, the Si/SnO 2 @CNF electrodes have smooth surfaces and non-destructive designs. Furthermore, after 1000 cycles, the cross-sectional thickness increases by approximately 21.2 %. Given their outstanding performance as energy storage materials, doubly modified silicon-based anodes have a wide range of possible uses. This research proposes a viable technical solution to increase the widespread usage of silicon anodes.
