In situ fabrication of graphene–carbon nanochain webs as anodes for Li-ion batteries

Carbon nanochain webs-sandwiched graphene has been successfully fabricated via in situ polymerization and subsequent carbonization. Such a novel nano–micro structure not only provides high conductivity, but also improves the cycling stability and rate capability during Li-ion storage. It shows a charge capacity of 1103.2 mA h g−1 at 0.05 A g−1 after 50 cycles.
