The invention relates to a positive material for a super
capacitor, a preparation method of the positive material and the super
capacitor employing the positive material. The positive material is prepared from an
active electrode material NiL<2>(H<2>O)<4>, a conductive agent, a binder and a
positive current collector, wherein L is 4-
pyridine carboxylate. The preparation method of the positive material comprises the following steps: mixing the
active electrode material NiL<2>(H<2>O)<4>, the conductive agent and the binder in a
beaker at the ratio; adding absolute ethyl
alcohol to the
beaker until the absolute ethyl
alcohol immerses the materials in the
beaker; stirring the beaker on a
magnetic heating stirrer;
coating the
positive current collector with the materials in the beaker by a scraping knife; and putting the coated
positive current collector into an electrically heated constant-temperature
drying oven at a constant temperature below 100 DEG C until the positive material is obtained. The invention further relates to the super
capacitor employing the positive material. The specific
capacitance of the super capacitor prepared from the positive material in an experimental condition can reach 1149F / g; and the super capacitor is relatively long in lifetime, can be widely applied to the fields of
consumer electronics, uninterrupted power supply systems,
hybrid power supply systems for electric vehicles and the like.
