Enhanced anode performances of the Fe3O4–Carbon–rGO three dimensional composite in lithium ion batteries

Abstract

A three dimensional composite was constructed by anchoring Fe(3)O(4) nanoparticles encapsulated within carbon shells onto reduced graphene oxide sheets, which exhibited enhanced anode performances in lithium ion batteries with a specific capacity of 842.7 mAh g(-1) and superior recycle stability after 100 cycles.

Photocatalytic activity of reduced graphene oxide/SnO2 nanocomposites prepared in ionic liquid

“…1 shows XRD patterns of the GO, RGO, SnO 2 and GTC. The GO pattern exhibited a sharp peak at an angle 2u of 11.3 corresponding to the (0 0 1) reflection of GO, confirming that GO forms a well-ordered layered structure [25,26]. After the microwave treatment, the peak at 2u = 11.3 disappeared and an amorphous diffraction peak at 2u of approximately 25 was observed.…”

Li3V2(PO4)3/graphene nanocomposite as a high performance cathode material for lithium ion battery

“…Compared to traditional carbon, graphene nanosheets, a singleatom-thick sheet of honeycomb carbon lattice, show a number of intriguing unique properties, such as superior electrical conductivity, high surface area, large surface-to-volume ratio, and good mechanical properties [31][32][33]. Recently, improved cycling stability and rate performances were reported when an electrode material was supported by graphene [34,35].…”

Li3V2(PO4)3@C/graphene composite with improved cycling performance as cathode material for lithium-ion batteries

“…This problem can be partly solved by metal doping [20][21][22] or mixing with electronically conductive materials such as carbon [23,24]. Compared to traditional carbon, graphene nanosheet (GNS) shows excellent electronic conductivity and has been demonstrated as truly effective conductive additive for LIBs [25,26]. Liu et al [27] prepared LVP/graphene composite which could delivered a high specific discharge capacity of 82 mAh g −1 at 50 C rate in the potential range of 3.0-4.3 V, indicated that GNS could greatly improve the rate performance of LVP.…”
