Nitrogen-incorporated ultrananocrystalline diamond and graphene nanowalls coated graphite and silicon anodes for long-life lithium ion batteries

Both conventional graphite and emerging new anode materials, such as silicon based anodes for lithium ion batteries have been coated with nitrogen-incorporated ultrananocrystalline diamond, graphene, and their hybrids. Novel micro- and nano-structures of the anodes enable the LIBs to survive repetitive charging and discharging by much higher number of cycles than those anodes without such innovative nano-carbon coatings. This paper presents the fabrication processes, excellent performance of the LIB anodes and their electrical and electrochemical properties.
