| الوصف: | International audience ; Microsupercapacitor electrodes with 3D architectures have drawn increasing interest in recent years due to their better energetic performances while maintaining a reduced footprint occupancy. Here, we report two different strategies to realize highly porous scaffolds of RuO2 on Si wafers, with areal enlargement factors exceeding 13000 cm 2 /cm 2. The 3D structures are synthesized via hydrogen bubble dynamic template at low temperature, onto which a conformal electrodeposition of hydrated RuO2 thin film is performed. The microsupercapacitor electrode exhibits a record areal capacitance of 24 F cm-2 with an incredible areal energy of 8.7 J cm-2 (i.e. 2.4 mWh cm-2), together with a high power of 354 mW cm-2 and an excellent cycling stability. These electrodes stand miles ahead from previously reported studies both in terms of their surface area and surface capacitance, making them suitable for IoT applications demanding high energy/high power density per footprint area. |
