(a) Cyclic voltammograms (five cycles) conducted in EC/DMC (50% v/v), containing 1 mol L−1 LiClO4, at 100 mV s−1 for the electrochemical PPy/CNT composite ((A) is the device before and (B) is the device after charge and discharge tests) and the chemical PPy/CNT composite ((C) is the device before and (D) is the device after charge and discharge tests). (b) Amplification of the chemical composite device ((C) and (D)) before and after the charge and discharge tests.
