Hybrid capacitors have am important role in supercapacitors, namely high power capabilities and prolonged cycle life, while having higher specific energy density than traditional one. Usually this is realized by assembling an asymmetric cell with an electric double layer capacitor and searching for alternative energy storage system using multivalent cations. Recently, a new group of 2D transition metal carbide is standing in a spotlight because it represents a type of 2D material that has demonstrated many possibilities in electrochemical energy storage applications. To full utilization, 2D metal carbide, Mxene, is hybridized with carbonaceous material such as graphene. Mxene/GO composites can provide hierarchical structure, which is benefit to the ion diffusion and decrease the charge transfer resistance. Due to these reasons, it can be considered as a promising electrode candidate for high energy storage system. |
