The growing demand for lithium has increased interest in sodium-ion batteries (SIBs) as a low-cost alternative to lithium-ion batteries. In this study, vertically aligned carbon nanotubes (VACNTs) were employed as the anode active material for SIBs. VACNTs were synthesized on Cu substrates by alcohol catalytic chemical vapor deposition, and the resulting VACNT/Cu was directly used as the anode to fabricate SIBs. Charge–discharge measurements revealed a discharge capacity of 117 mAh/g after 10 cycles, exceeding that of conventional graphite anodes.
