CdCO3/Carbon nanotube nanocomposites as anode materials for advanced lithium-ion batteries

• The CdCO3/carbon nanotube nanocomposites are synthesized via a facile solution method.
• CdCO3 and CdCO3/carbon nanotube nanocomposites could be used as high capacity anode for lithium ion batteries with an alloying/de-alloying mechanism.
• Compared to the pure CdCO3, the CNTs/CdCO3 nanocomposites showed a improved cycle stability.

Well dispersed CdCO3/carboxylated carbon nanotubes (CNTs) nanocomposites are synthesized via a facile solution method. As a novel anode material for lithium-ion batteries, the CdCO3/CNTs nanocomposites deliver an initial reversible capacity of 876 mAh g−1 and a better cycle ability. The superior electrochemical performance can be attributed to its unique hierarchy architecture, which facilitate the electron transport and accommodate the large volume change during the alloying/de-alloying reactions.
