The synthesis of a hybrid graphene–nickel/manganese mixed oxide and its performance in lithium-ion batteries

Magnetic Nanocomposites Formed by FeNi3 Nanoparticles Embedded in Graphene. Application as Supercapacitors

“…Additionally, high-performance capacitances have been described for a hybrid graphene-nickel/ manganese mixed oxide nanocomposite derived from a NiMn-LDH when used as an anode material for Li-ion batteries. [ 23 ] In our opinion, these precedents illustrate the potential of LDHbased composites for developing more effi cient supercapacitors. These electrochemical devices have attracted considerable interest in recent years because of their high power density, long cycle life, and low maintenance cost.…”

Simple fabrication of strongly coupled cobalt ferrite/carbon nanotube composite based on deoxygenation for improving lithium storage

“…Furthermore, when an Fe 2+ -containing LDH precursor was employed to generate neat MFe 2 O 4 spinel ferrite, the transformation of Fe 2+ to Fe 3+ may occur causing the reduction of the oxygen-containing groups on the oxidized CNTs surface. As a result, it could be anticipated that LDH precursor with decomposition behavior would exhibit stronger chemical interactions with the oxidized CNTs during the calcining process [30,31], even produce an 'oxygen bridge' linkage [32]. However, to our best knowledge, the deoxygenation of oxidized CNTs originated from the reducting effect of Fe 2+ cations had not been reported so far.…”

Novel route to synthesis of N-doped graphene/Cu–Ni oxide composite for high electrochemical performance

“…7), the intensities of sp 2 and sp 3 C-C bonds (284.4 eV) are obviously increased and the bonds associated with oxidized carbon (including C-N at 285.5 eV, C-O at 286.7 eV, C@O at 287.7 eV, and O-C@O at 288.9 eV) are decreased, indicating that GO has been deoxygenated to form NG in the composite (Fig. 7) [47,48].…”
