Recent progress in graphene assisted vanadium oxide nanocomposi 2026 Next Ma

Graphene assisted Vanadium oxide (VOx) nanocomposites have gathered significant interest as potential electrode materials in the next-generation Lithium-ion Batteries (LIBs) because of the synergistic merits of the two constituents in which graphene tends to possess the best electrical conductivity and mechanical strength, whereas vanadium oxides tend to have a high discharge capacity and flexible redox properties. Recent work describes various synthesis strategies such as solvothermal, hydrothermal, and co-precipitation, all of which have a great effect on morphology, interface bonding, and charge-transport properties of such materials. Graphene is important in improving VOx stability, rate capability, and structural stability during repeated cycling. Representative performances highlight that V2O5/rGO composites are capable of delivering a discharge capacity of 280 mAhg−1 with 91% capacity retention over 1000 cycles, whereas layered V2O5 nanofibers yield a discharge capacity of 250.7 mAhg−1 with 82% capacity retention over 150 cycles. Such nanocomposites, used as cathode, anode, and hybrid electrodes, show high potential in enhancing capacity, efficiency, and long-term stability. Although some challenges such as structural degradation and scalability remain, there are new opportunities to enhance high-performance, long-lasting LIB technologies through approaches like defect engineering, 3D graphene structures, and solid-state designs.
