| 英文摘要 | cotton stalk based activated carbon (ac) was prepared from xinjiang, china by h3po4 as activating reagent. in order to improve electrochemical properties of ac, a series of ac/mno2 (electrolytic manganese dioxide)/ac composites with different mno2 contents were prepared. the samples specific surface area and pore distribution were characterised by brunauer, emmett and teller (bet); the structure and morphology were characterised by x-ray diffraction (xrd) and scanning electron microscope (sem) respectively. moreover, the improvements of activated carbon modified by mno2 were confirmed by the experiment of galvanostatic current charge/discharge, cyclic voltammograms and alternating current impedance tests respectively. the results show that the specific capacitance (169 f g(-1)) of the composite material electrode (the contents of mno2 is 5%) would be higher in 1.0 mol l-1 et4nbf4/an electrolyte at 2.0 a g(-1) than other composite materials, which is 39% higher than the present study. the capacitance was kept more than 99.2% after 500 cycles and still higher than that of activated carbon materials. |
