Three-dimensional carbon nanotubes for high capacity lithium-ion batteries

Free‐standing nitrogen‐doped graphene‐carbon nanofiber composite mats: electrospinning synthesis and application as anode material for lithium‐ion batteries

“…14 Graphite, as the current main anode material for commercial LIBs, still maintains some fatal deficiencies, such as a poor rate and cycle capacity, which can not meet the increasing demand of the LIBs. 15 Therefore, multifarious carbonaceous materials, especially nanostructured carbon-based materials, such as graphene sheets, 16 graphene nanoribbons, 17 carbon nanotubes, 18,19 carbon nanofibers (CNFs), 20 and carbon nanospheres 21 have received plenty of attention due to the merits of dynamic advantages relative to the bulk counterparts, 22 abundant resources and environment-benign. 23 As two important members in the carbon material family, graphene and CNFs have shown outstanding advantages as anode materials in LIBs.…”

In situ fabrication of a graphene-coated three-dimensional nickel oxide anode for high-capacity lithium-ion batteries

“…Our previous experiment demonstrated how 3-dimensional (3D) structures could enhance the areal capacity of electrodes in LIBs. 33,34 By following this concept, we fabricated a novel structure of graphene-coated 3D NiO-Ni anode through a simple two-step thermal chemical vapor deposition (CVD) method, in which graphene layers were grown directly on a NiO-Ni structure. In this structure, porous 3D Ni substrate offered high surface area to accommodate large loading of NiO; in addition, the porous structure facilitated lithium ion diffusion within NiO.…”

Liquefied walnut shell-derived carbon nanofibrous mats as highly efficient anode materials for lithium ion batteries

“…[1][2][3][4] For the electrodes in LIBs, carbon materials have been holding a predominant position and been believed to be the most prospective for industrialization because of their low-cost, easy accessibility, and processability. 5,6 To date, various types of carbon materials such as carbon nanotubes, 7 carbon spheres, 8 carbon bers, 9 and porous carbon 10 have been investigated as the major anode materials for LIBs because of their high conductivity and abundant specic surface area. However, the high cost and non-renewability of the carbon precursors (such as petroleum, polyacrylonitrile, coals, etc.)…”
