Nickel-titanium oxide as a novel anode material for rechargeable sodium-ion batteries

Abstract

This is the first report on the use of metal titanate (NiTiO₃), in the form of ultrafine nanoparticles, as an anode material for Na-ion rechargeable batteries. NiTiO₃ was prepared using a simple and economical hydrothermal process, and the ultrafine nanoparticles exhibited a high reversible capacity and an excellent cycling performance.
