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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
