Abstract

Abstract In this work, Li<inf>2</inf>FeSiO<inf>4</inf> nanoparticles with two types of morphologies, spherical and rod-shaped, were prepared via a facile water/ethylene-glycol-based solvothermal method by using different kinds of iron sources and surfactants. When evaluated as a cathode material for lithium-ion batteries, carbon-coated Li<inf>2</inf>FeSiO<inf>4</inf> nanospheres exhibited good cycling stability and large Li storage capacities, delivering 150 and 200 mA h g<sup>-1</sup> at room temperature and 55 °C, respectively.
