“…The VM‐700 shows a capacity retention of 92% after 200 cycles with respect to the second cycle. The VM‐700 electrode also shows superior performance over most vanadium‐based electrodes such as V 2 O 3 ‐OMC, V 2 O 3 ‐CNF, V 2 O 3 ‐RGO, and so on (see Table S1 in the Supporting Information for further comparison). Although our electrode does not show best electrochemical performance, its method is the simplest in the listed references (Table S1, Supporting Information).…”

Recently, researchers have made significant advancement in employing transition metal compound hybrids as anode material for lithium-ion batteries and developing simple preparation of these hybrids. To this end, this study reports a facile and scalable method for fabricating a vanadium oxide-nitride composite encapsulated in amorphous carbon matrix by simply mixing ammonium metavanadate and melamine as anode materials for lithium-ion batteries. By tuning the annealing temperature of the mixture, different hybrids of vanadium oxide-nitride compounds are synthesized. The electrode material prepared at 700 °C, i.e., VM-700, exhibits excellent cyclic stability retaining 92% of its reversible capacity after 200 cycles at a current density of 0.5 A g and attractive rate performance (220 mAh g ) under the current density of up to 2 A g . The outstanding electrochemical properties can be attributed to the synergistic effect from heterojunction form by the vanadium compound hybrids, the improved ability of the excellent conductive carbon for electron transfer, and restraining the expansion and aggregation of vanadium oxide-nitride in cycling. These interesting findings will provide a reference for the preparation of transition metal oxide and nitride composites as well.

“…This implies that it may be possible to further increase the capacity of both V 2 O 3 ‐0.5CA and V 2 O 3 /G‐0.5CA by adding more graphene, avoiding high extent of agglomeration that possibly allowing to have even better performance. For example, the performance of V 2 O 3 /G‐0.5CA could be boosted up to V 2 O 3 ‐rGO and V 2 O 3 /CFC composites by increasing rGO content about ∼44 wt.%. In addition, V 2 O 3 /G‐0.5CA synthesis method is relatively cheaper, simple and promising for bulk yield compared other illustrated advanced methods in Table .…”

A series of V2O3, V2O3/C and V2O3/G composite powders are prepared by simply annealing the reaction mixture containing ammonium metavanadate (0.1 M), reduced graphene oxide (rGO, 0.1 M) and citric acid (CA, 0.0, 0.1, 0.3 and 0.5 M) at 500 °C for 8 h under Ar flow. A variety of characterization techniques are used to investigate the structural, physiochemical features and electrochemical performance of the powders. The reaction mixture without rGO led to the formation of V2O3 at 0.1 M of CA and V2O3/C at 0.3 and 0.5 M of CA. As anodes of lithium‐ion coin cell batteries, V2O3, V2O3/C and V2O3/G composite electrodes exhibit an increase in capacity with increasing concentrations of CA. The increase in capacity is mainly attributed to the carbonization of CA and the declining crystallinity of V2O3. V2O3/C and V2O3/G prepared at 0.5 M of CA outperformed all other control compounds. The V2O3/C and V2O3/G delivered reversible capacities of 585 and 420 mAh g−1 respectively, during the first cycle with a current density of 50 mA g−1. The respective capacities after few initial cycles continuously increased to 608 and 463 mAh g−1 at the end of the 100th cycle.
