Abstract

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.
