Among various pseudo capacitive materials, manganese dioxide (MnO2) is a promising electrode material because of its high theoretical specific capacitance, abundant resources, low-cost, and eco-friendliness. But the poor conductivity and less electron transport properties of MnO2 limited their practical applications. The high power proton irradiation can effectively modify the electronic properties and surface states of the materials, also the irradiation can caused defects in the materials. Impurities in a crystal constitute structural imperfections which can alter electrical and mechanical properties of the materials. Moreover the irradiation creates secondary-electron charge carriers, and thus affects electrical properties of the materials, even it can improve the conductivity of the materials. We researched about electronic properties of the proton irradiated MnO2 by fabricating electrodes for super capacitor and checked the modifications of MnO2 nanostructure. |
