Cobalt‐Doped FeS 2 Nanospheres with Complete Solid Solubility as a High‐Performance Anode Material for Sodium‐Ion Batteries
Considering that the high capacity, long‐term cycle life, and high‐rate capability of anode materials for sodium‐ion batteries (SIBs) is a bottleneck currently, a series of Co‐doped FeS 2 solid solutions with different Co contents were prepared by a facile solvothermal method, and for the first time...
