Abstract

With KOH as precipitator to prepare Aluminum doped Co3O4,X-ray diffraction indicated that the doping Al did not change the crystal structure of Co3O4.Electrochemical properties of the sample were tested by cyclic voltammetry and constant-current charge/discharge.The results showed that the chemical doping improved the specific capacitance.When the mol ratio of Co(Ⅱ) with Al(Ⅲ)was 1∶0.05,the specific capacitance was up to 518.07 F/g within 0～400 mV potenitial at current density 5 mA/cm2.
