A binder-free Ge-nanoparticle anode assembled on multiwalled carbon nanotube networks for Li-ion batteries.
Germanium (Ge) nanoparticle-multiwalled carbon nanotube (MWCNT) anodes are fabricated through the anchoring of Ge on the surface of electrophoretically pre-deposited MWCNT networks via a thermal evaporation process. This Ge-MWCNT nanocomposite displays a large reversible capacity of over 800 mA h g(-1) at 1 C even after 200 cycles.
