Ultrathin carbon-coated FeS2 nanooctahedra for sodium storage with long cycling stability

Author affiliations

Abstract

Uniform and porous ultrathin-carbon-coated pyrite (FeS2@C) nanooctahedra have been fabricated via a facile solvothermal method with subsequent carbon-coating-annealing and acid-pickling steps. Benefitting from their high conductivity, short Na+ diffusion distance, large surface area, and robust structure stability, the FeS2@C electrodes delivered a high specific capacity, excellent rate capability and superiorly stable cycling performance, suggesting a potential application in advanced sodium ion batteries.
