Abstract Scope |
The abundance of functionally diverse two-dimensional (2D) materials in the form of nanoflakes has prompted a search for effective strategies to enhance the electrochemical charge storage properties of layered oxides. One promising approach is to create stable 2D heterointerfaces with conductive phases, such as graphene and MXenes. In this study, a novel Li+ ion-driven assembly technique was used to stack redox-active bilayered vanadium oxide (BVO) nanoflakes with reduced graphene oxide (rGO) nanoflakes in water. The result is the formation of stabilizing 2D BVO/rGO heterointerfaces, which lead to the significantly improved rate capability and capacity retention of the produced electrodes. This work demonstrates the potential of cation-driven assembly in stacking a diverse range of exfoliated 2D materials, leading to the creation of novel 2D heterostructures with superior properties. These findings hold promise for a wide range of technological applications. |
