英文摘要 | Ni(OH)2-Co(OH)2 was obtained by an easy simple liquid coprecipitation method. After calcination, the Co3O4-NiO composite particles were gotten, then modified by ethylenediamine. And the dispersion of Co3O4-NiO particles improved, morphology was flake, it formed loose mesoporous structure among each particles. Meanwhile, electrochemical supercapacitors properties of Co3O4-NiO electrode material were tested. The consequence manifested that the Co3O4-NiO composite particles showed excellent electrochemical performance and its single electrode specific capacitance was up to 1202 F/g at the potential window of 0-0.4 V, which increased 171 F/g compared with the unmodified. |
