20140170483 | METHOD FOR THE PREPARATION OF GRAPHENE/SILICON MULTILAYER STRUCTURED ANODES FOR LITHIUM ION BATTERIES - Multilayer structures with alternating graphene and Si thin films were constructed by a repeated process of filtering liquid-phase exfoliated grapheme film and subsequent coating of amorphous Si film using plasma-enhanced chemical vapor deposition (PECVD) method. The multilayer-structure composite films, fabricated on copper current collectors, can be directly used as anodes for rechargeable lithium-ion batteries (LIBs) without the addition of polymer binders or conductive additives. Fabricated coin-type half cells based on the new anode materials easily achieved a capacity almost four times higher than the theoretical value of graphite even after 30 cycles.
