Abstract

The invention discloses a method for preparing a super capacitor with double conductive networks. The method comprises the following steps of firstly, preparing Gly-Na2SO4-Mo electrolyte, and then integrally preparing a Gly-Na2SO4-Mo / Gly-Mo-PPy double conductive network super capacitor; according to the Gly-Na2SO4-Mo / Gly-Mo-PPy flexible supercapacitor with the double conductive networks and of which the electrolyte and the electrode having the same matrix, Gly-Na2SO4-Mo is the electrolyte, and Gly-Mo-PPy is an electrode material growing on the electrolyte. the hydrophilic Gly and the polypyrrole are embedded into the electrode to form an ion conductive network together with the electrolyte; Mo and PPy form an electronic conductive network in the electrode, and the performance of the supercapacitor is remarkably improved under the action of the double conductive networks. Gly-Mo exists in the electrolyte and the electrode, so conductivity and the performance of the supercapacitor are improved.
