原子层沉积铝掺杂ZnO纳米膜在超级电容器中的应用
Atomic Layer Deposited Al-doped ZnO Nanomembranes for Supercapacitor Application
摘要
Abstract
Electrochemical supercapacitors are continuously taking part to fulfill energy requirements .In this study , we described the potential application of Al-doped ZnO (AZO ) nanomembranes in supercapacitor .The nanomembranes were fabricated by atomic layer deposition and their structures were stacks of alternate ultrathin ZnO and Al2O3 layers with different cycle numbers . The ultrathin AZO nanomembranes were well electrochemically responded and the results demonstrated the (10:1)10 sample had the most suitable behavior of charging and discharging .The best specific capacitance of the AZO nanomembranes supercapacitor was 61 F·g -1 at 1 A·g -1 in 6M KOH electrolyte .As for practical application ,we demonstrate the supercapacitor can flash a red LED light for more than 60 min .The AZO nanomembranes have potential in supercapacitor and could be engaged in future wearable energy storage device .关键词
