Graphitic carbon-wrapped NiO embedded three dimensional nitrogen doped aligned carbon nanotube arrays with long cycle life for lithium ion batteries

“…These results can be ascribed to the electrochemical activation process during the cycle process, which is commonly observed for transition metal oxides electrodes. 21,48–50 …”

“…These results can be ascribed to the electrochemical activation process during the cycle process, which is commonly observed for transition metal oxides electrodes. 21,[48][49][50] In addition, it should be noted that when using pure NiO or NACNTs separately as the electrode, they exhibit very low discharge capacities of 64 and 202 mA h g À1 respectively. This indicates that our strategy is very benecial for promoting the cycling stability of the NiO-based active material.…”

“…Hybridizing NiO with carbon to improve the Li + storage properties and the overall electronic conductivity is another strategy. 8,12,14,17,18 Up to now, carbon nanotubes (CNTs), 13,16,19 graphene, [20][21][22][23] ordered mesoporous carbon (CMK-3), 14 amorphous carbon 8,12 and carbon ber 24,25 are oen used to build carbon/NiO nanostructure. Among these options, CNTs are of particular interest because of their favorable structure exibility, large specic surface area, good electrolyte accessibility and excellent electrical conductivity.…”

Green Synthesis of a Reduced‐Graphene‐Oxide Wrapped Nickel Oxide Nano‐Composite as an Anode For High‐Performance Lithium‐Ion Batteries

“…Significant volume of researches have been carried out since last decade on graphene and its derivatives with TMOs as composite anode materials in LIBs [1,13–37] . However, most of these studies involve the synthesis of graphene to fabricate composites either by chemical method (oxidation of graphite followed by reduction) or chemical vapour deposition (CVD) route [13–37] . Sophisticated experimental setup, use of inflammable gases, substrate selectivity and high cost are the major challenges for bulk scale production of graphene in CVD process, limiting it to academic interest only.…”

“…It is also an electrochromic material with a high coloration efficiency. [22][23][24] NiO x has a high-temperature coefficient of resistance, high theoretical specific capacity of 718 mA h g −1 (compared to 372 mA h g −1 for graphite 25 ) and high catalytic activity, making the material actively explored for supercapacitors, 26 thermistors, 27 Li-ion batteries, 28 and catalysts for CO or H 2 O oxidation. 29,30 As a simple binary oxide, NiO x thin films can be grown with a wide range of deposition techniques.…”
