Anderson-typed POM-derived FeS2/MoS2 heterostructure hybridized with graphene for sodium-ion batteries anodes

Benefiting from synergistic hetero engineering and graphene integration, the FeS 2 /MoS 2 /rGO-0.5 anode demonstrates superior electrochemical performance for SIBs (334 mAh g −1 at 10 A g −1 , 318 mAh g −1 after 500 cycles at 5 A g −1 ).
