我们描述了一种原位制造分层 Fe3O4 纳米团簇-GA 的新策略。 Fe3O4 NCs-GA具有优异的倍率性能（在0.1C、12C和35C倍率下获得的可逆容量分别为1442、392和118 mAh g(-1)），并且在5.2 A g(-1) (6C)的电流密度下经过300次循环可达到577 mAh g(-1)的高可逆容量。
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).
