Hybrid capacitors have played an important role in energy storage, 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. However, existing carbon based electrodes for volumetric capacitances have a limitation at around 60 F cm-3 . 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. |
