文摘

Binder-free combination of highly conductive Cu bridges with amorphous TiO₂ nanotube arrays for lithium ion battery anode were designed and achieved via one-step facile electrodeposition. The obtained composite Cu/TiO₂ nanotubes electrode was studied in terms of XRD, SEM, EDX, galvanostatic charge/discharge, cycle stability, rate performance, and AC impedance. As expected, the composite electrode delivered higher discharge capacity, rate performance, and cycle stability than the bare one, possibly due to improved electrical conductivity and the synergy effect between conductive Cu bridges and amorphous TiO₂ nanotube arrays.KeywordsConductive Cu bridgesAmorphous TiO₂ nanotube arraysOne-step electrodepositionAnodeLithium ion battery
