文摘

Rationally assemble a Fe3O4 NS@MWCNTs/r-GO layer-by-layer paper-like electrode. The MWCNTs can be served as a soft and flexible carbon coating. The r-GO layer is the key to form the free-standing paper, and prevent agglomeration. After 300 cycles at 3.2 A g−1 the capacity remaining above 420 mAh g−1.
