Abstract : The concept of a hybrid nanostructured collector made of thin vertically aligned carbon nanotubes CNTs decorated with Si nanoparticles provides high power density anodes in lithium-ion batteries. An impressive rate capability is achieved due to the efficient electronic conduction of CNTs combined with well defined electroactive Si nanoparticles: capacities of 3000 mAh g−1 at 1.3C and 800 mAh g−1 at 15C are achieved.

Keywords : silicon carbon nanotubes nanostructure lithium-ion batteries high rate capability
