Abstract

Due to rich redox sites and high electronic conductivity, multi-metal sulfides are considered as a competitive candidate for energy storage and conversion. Recently, nanostructure engineering and composition control are usually employed to enhance the electrochemical performance of metal sulfides. Herein, Fe3Ni6S8 solid solution anchored on N-doped carbon matrix (denoted as Fe3Ni6S8/N
