Realizing High‐Performance Li/Na‐Ion Half/Full Batteries via the Synergistic Coupling of Nano‐Iron Sulfide and S‐doped Graphene

Iron sulfide (FeS) anodes are plagued by severe irreversibility and volume changes that limit cycle performances. Here, a synergistically coupled hybrid composite, nanoengineered iron sulfide/S‐doped graphene aerogel, was developed as high‐capacity anode material for Li/Na‐ion half/full batteries. T...
