Hierarchically porous Zn_0.76Co_0.24S/CoS heterostructures confined in N,S-co-doped carbon as high-performance anodes for sodium-ion batteries

Abstract

Owing to the favorable merits of substantial capacity, low price, and eco-friendliness, metal sulfides have been widely desired as prospective anodes for sodium-ion batteries. However, the huge volumetric variation, inferior...
