【 摘 要 】

Supercapacitor devices are interesting owing to their broad range of applicability from wearable electronics to energy storage inelectric vehicles. One of the key parameters that affect the efficiency of supercapacitor devices is selecting the ideal electrode material for a specific application. Regarding this, recently developed metal oxides, specifically nanostructured ZnO, and MXenes withtheir defect structures, size effects, as well as optical and electronic properties have been presented as electrode material in supercapacitor devices. The discussion of MXenes along with ZnO, although different in chemistry, also highlights the differences indimensionality when it comes to defect-driven effects, especially in carrier transport. The volume under the influence of the defectcenters is expected to be different in bulk and 2D structures, regardless of composition. Hence, analysis and discussion of both materials provide a fundamental understanding regarding the manner in which 2D structures are impacted by defects compared tobulk. Such an approach would therefore serve the scientific community with the material design tools needed to fabricate the nextgeneration of supercapacitor devices.
