چکیده

SnO2 nanotubes are synthesized via an oxalate-assisted "redox etching and precipitating" route between MnOOH nanowires and Sn2+ ions. The addition of oxalate is found to be crucial to guide the formation of uniform SnO2 nanotubes. To further improve the conductivity and stability, the as-obtained SnO2 nanotubes are coated with a thin carbon layer. The resulting carbon-confined SnO2 nanotubes possess superior rate performance as an anode material for lithium-ion batteries.

Solvent-Free Synthesis of Uniform MOF Shell-Derived Carbon Confined SnO2 /Co Nanocubes for Highly Reversible Lithium Storage.

Tin dioxide (SnO2 ) has attracted much attention in lithium-ion batteries (LIBs) due to its abundant source, low cost, and high theoretical capacity. However, the large volume variation, irreversible conversion reaction limit its further practical application in next-generation LIBs. Here, a novel solvent-free approach to construct uniform metal-organic framework (MOF) shell-derived carbon conf...

Reserving Interior Void Space for Volume Change Accommodation: An Example of Cable‐Like MWNTs@SnO2@C Composite for Superior Lithium and Sodium Storage

Reserving interior void space in the cable-like structure of multiwalled carbon nanotubes-in-SnO2-in-carbon layer (MWNTs@SnO2@C) is reported for the first time. Such a design enables the structure performing excellent for Li and Na storage, which benefit from the good electrical conductivity of MWNTs and carbon layer as well as the reserved void space to accommodate the volume changes of SnO2.
