Electrophoretically deposited nickel titanate/CNT composite as promising anode for lithium/sodium ion batteries

In this study, we have demonstrated that electrophoretically fabricated NiTiO3 (NTO)/CNT composite is a viable negative electrode for lithium and sodium ion batteries, with favorable electrochemical performance. NTO/CNT exhibited initial discharge capacity of 1032 mAhg−1 and 751 mAhg−1 at 100 mAg−1 with a retained capacity of ∼ 412 mAhg−1 and ∼ 180 mAhg−1 even after 100 cycles against lithium and sodium ion respectively. CNT helps in buffering the volume fluctuations by giving structural stability and enables good cycle life performance. Also such good performance can be ascribed to the porous microstructure, good adherence property with the current collector and uniform active material distribution with carbon black and CNT on the deposited film.
