12. Discussion
To prove that AC/CNT is a better electrode compared to AC and CNT electrodes, the Csp results of AC and CNT had been measured separately. It (slide 8)confirms that pure AC is an EDLC types even though it did not show a perfect rectangular shape.
By using the same method of fabricating AC/CNT electrode, pure AC gives out Csp of 1.27 F g-1 at 1 mV s-1. Hence, comparing the Csp values of AC and AC/CNT, it is proven that AC/CNT is a better combination to be used as an electrode in a device.
