Chemical activation of bamboo activated carbon (BAC) based on microwave-ultrasonic activation for supercapacitor application / Norakmalah Mohd Zawawi

Activated carbon (AC) has been explored as a raw material for supercapacitor due to its characteristic of having porosity and electrical conductivity, which could liberate a high power. From high surface area and pores size, it leads to a high specific capacitance values more than 70 F/g. High adsor...
