Urchin-like hierarchical spheres of FeSe2 embedded in TiN/C composite covered by CNTs as anodes for sodium-ion storage Transition-metal selenides are considered promising anode materials for sodium-ion batteries due to their high theoretical capacity based on multielectron conversion reactions. However, their low intrinsic electrical conductivity and severe volume variations result in poor cycling performance and rate capability.
