Abstract

A novel microstructure of anode materials for lithium-ion batteries with ternary components, comprising tin (Sn), rice husk-derived silica (SiO₂), and bronze-titanium dioxide (TiO₂(B)), has been developed. The goal of this research is to utilize the nanocomposite design of rice husk-derived SiO₂ and Sn nanoparticles self-assembled on TiO₂(B) nanorods, Sn-SiO₂@TiO₂(B), through simple chemical route methods. Following that, the microstructure and electrochemical performance of as-prepared products were investigated. The major patterns of the X-ray diffraction technique can be precisely indexed as monoclinic TiO₂(B). The patterns of SiO₂ and Sn were found to be low in intensity since the particles were amorphous and in the nanoscale range, respectively. Small spherical particles, Sn and SiO₂, attached to TiO₂(B) nanorods were discovered. Therefore, the influence mechanism of Sn-SiO₂@TiO₂(B) fabrication was proposed. The Sn-SiO₂@TiO₂(B) anode material performed exceptionally well in terms of electrochemical and battery performance. The as-prepared electrode demonstrated outstanding stability over 500 cycles, with a high discharge capacity of ∼150 mA h g^-1 at a fast-charging current of 5000 mA g^-1 and a low internal resistance of around 250.0 Ω. The synthesized Sn-SiO₂@TiO₂(B) nanocomposites have a distinct structure, the potential for fast charging, safety in use, and good stability, indicating their use as promising and effective anode materials in better power batteries for the next-generation applications.
