| Summary: | The morphology and electrochemical characteristics of an
electrode based on a SnOx
/Sn@MWCNTs composite consisting
of multi-walled carbon nanotubes (MWCNTs) and metal oxide
particles (Sn/SnOx
) with a core-shell structure are studied. This
composite shows good electrochemical characteristics as the
anode material for lithium-ion batteries, providing 1494 mAh/g
as the first discharge capacity and 634 mAh/g discharge capacity
after 30 charge/discharge cycles (72 % capacity retention). The
stable characteristics of such a material are due to the high
interfacial adhesion between functionalized MWCNTs and Sn/
SnOx
nanoparticles, as well as their unique gradient structure. |
