The electrochemical supercapacitors; (ESs) were assembled with carbon nanotube (CNT) and zinc oxide (ZnO) composite as the electrode and gel polymer as the electrolyte. The CNT film was fabricated using screen-printing method and ZnO was deposited by ultrasonic spray pyrolysis (USP) in different time from 2 to 30 min. The analysis of cyclic voltammetry (CV) shows that the ESs of CNTs with ZnO deposited for 5 min exhibited the optimized electrochemical capacitive properties, and the specific capacitance reaches 126.3 F/g by CV test, much better than that of the pure CNTs.
