The TiO2-bronze/nitrogen-doped graphene nanocomposites have the potential for fast-charging and have high stability, showing potential as an anode material in advanced power batteries for next-generation applications.

A novel microstructure of anode materials for lithium-ion batteries with ternary components, comprising tin (Sn), rice husk-derived silica (SiO 2 ), and bronze-titanium dioxide (TiO 2 (B)), has been developed. The goal of this research is to utilize the nanocomposite design of rice husk-derived SiO 2 and Sn nanoparticles self-assembled on TiO 2 (B) nanorods, Sn–SiO 2 @TiO 2 (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 TiO 2 (B). The patterns of SiO 2 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 SiO 2 , attached to TiO 2 (B) nanorods were discovered. Therefore, the influence mechanism of Sn–SiO 2 @TiO 2 (B) fabrication was proposed. The Sn–SiO 2 @TiO 2 (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–SiO 2 @TiO 2 (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.

By combining rice husk-derived nano-silica and reduced graphene oxide and then polymerizing PANI by in situ polymerization, we created polyaniline-coated rice husk-derived nano-silica@reduced graphene oxide composites with excellent electrochemical performance.

Novel anode materials for lithium-ion batteries, nanocomposites of Sn (or SnO₂) and SiO₂ with graphene-based sheets (GO, rGO and NrGO), were synthesized by a facile and low-cost technique. The capacity of all composites was relatively high as compared to traditional graphite.
