Preparation of MoP₂ nanoparticles as a novel anode material for sodium ion batteries

Abstract

MoP₂ nanoparticles were synthesis through solid state reaction route in a sealed quartz tube followed by acid washing. The obtained nanoparticles were evaluated as anode materials for sodium-ion batteries for the first time. The as-prepared material delivers a reversible discharge capacity of 205 mA h g⁻¹ at a current rate of 40 mA g⁻¹. It also exhibits a good cyclability as a negative electrode material. This contribution demonstrates that MoP₂ is a promising negative electrode material for the development of rechargeable long-life sodium-ion batteries.
