In situ preparation of 3D graphene aerogels@hierarchical Fe3O4 nanoclusters as high rate and long cycle anode materials for lithium ion batteries

We describe a novel strategy for in situ fabrication of hierarchical Fe3O4 nanoclusters-GAs. Fe3O4 NCs-GAs deliver excellent rate capability (the reversible capacities obtained were 1442, 392 and 118 mA h g(-1) at 0.1C, 12C and 35C rates), and a high reversible capacity of 577 mA h g(-1) over 300 cy...

Zusammenfassung:We describe a novel strategy for in situ fabrication of hierarchical Fe3O4 nanoclusters-GAs. Fe3O4 NCs-GAs deliver excellent rate capability (the reversible capacities obtained were 1442, 392 and 118 mA h g(-1) at 0.1C, 12C and 35C rates), and a high reversible capacity of 577 mA h g(-1) over 300 cycles at the current density of 5.2 A g(-1) (6C).
