One-pot synthesis of a composite of monodispersed CuO nanospheres on carbon nanotubes as anode material for lithium-ion batteries.

Highlights: [•] Composite of functionalized carbon nanotubes (CNTs) with CuO nanospheres is prepared. [•] Monodispersity, shape and size of CuO particles is specifically controlled to achieve high electrochemical performance. [•] The co-existence of CNTs and CuO matrix is clearly seen from TEM image. [•] High discharge capacity of 638mAh/g after 50 cycles. [•] 76% coulombic efficiency after 50cycles with a very small loss of charge capacity. [Copyright &y& Elsevier]
