%X Different activated carbon nanotubes (ACNTs) were obtained with different activating agent dosages using KOH as the activating agent. All the ACNTs were used as the electrode materials of electrochemical super capacitors and the ACNTs electrochemical capacitances were tested by DC-5C battery testing instrument. The results showed that the ACNTs electrochemical capacitance changed with modifying the mass ratio of KOH and carbon nanotubes (CNTs), and had a maximum at mKOH/mCNTs=3. At the same time, ACNTs were characterized by TEM, HRTEM and N2 auto adsorber. And the results showed that the relationship between the ACNTs electrochemical capacitance and activating agent dosage was closely correlated with the ACNTs BET specific surface area. Namely, the ACNTs BET specific surface area was important to their electrochemical capacitance.
