I am a high school student, and my team and I are developing a small capacitor using waste materials. We would appreciate any critiques or questions regarding our capacitor design and performance.
**Brief description:**
The device is a single-layer capacitor using paper soaked in NaOH as the electrolyte. Electrochemical characterization was conducted using cyclic voltammetry (CV) and galvanostatic charge–discharge (GCD) tests.
**Specific capacitance:**
5 mV/s: 3.383 F/g
10 mV/s: 1.220 F/g
**Power density:**
5 mV/s: 809.707 W/kg
10 mV/s: 1152.054 W/kg
**Energy density:**
5 mV/s: 0.899 Wh/kg
10 mV/s: 0.640 Wh/kg
