- •
Low density VACNT array are applied as matrix of high power micro-supercapacitor.
- •
Through introducing MnO2, the capacitance exhibit tremendous improvement.
- •
Energy density has been increased from 0.017 to 0.426 mWh cm−3 at 50000 mV s−1.
- •
Due to asymmetric design of the MSC, potential window is increased to 1.2 V.
