- Abstract
- We demonstrate a facile synthetic procedure to obtain Fe3O4/MWCNT (MWCNT = multiwalled carbon nanotube) composite electrode via the one-pot colloidal preparation method at 180 degrees C with a surface functionalized MWCNT. Fe3O4 nanoparticles were successfully precipitated on the surface of MWCNT with uniform size of approximately 10 nm. Fe3O4/MWCNT composite electrode exhibits a better reversible capacity, cycle life, and rate capability compared with the Fe3O4 powder electrode by higher electronic conductivity and stable structural properties with the support of MWCNT.
