Abstract

The invention discloses a manufacturing method of a carrollite-based super capacitor electrode plate. The method mainly comprises the following steps of successively adding a carrollite active substance and a coupling agent into absolute ethyl alcohol; then adding a cleaned and dried foamed nickel plate, carrying out ultrasonic treatment and vacuum drying, then pressing into sheets; and then carrying out vacuum heat treatment to obtain the carrollite-based super capacitor electrode plate. A capacitance value of the carrollite-based super capacitor electrode plate is more than 750F/g and an electron transfer resistance value is less than 0.2 ohm, and the active substance has good connectivity and is not easy to fall off.

Description

technical field [0001] The invention belongs to the field of electrode preparation, and in particular relates to a method for preparing a sulfur-copper-cobalt mineral-based supercapacitor electrode plate. Background technique [0002] Sulfur copper cobalt ore (CuCo 2 S 4 ) combines the advantages of both Cu and Co metal sulfides to demonstrate performance advantages. Its preparation methods mainly include solution method and hydrothermal synthesis method. Sulfur copper cobalt ore (CuCo 2 S 4 ) overcomes the limitations of the complex synthesis process of traditional multifunctional nanocomposites in preparation, abandons the traditional solid-state method and uses a simple hydrothermal method to prepare copper-copper-cobalt (CuCo) with various shapes. 2 S 4 ) nanoparticles, which reduce the synthesis conditions while improving safety, and have made a breakthrough in the preparation method. CuCo 2 S 4 The electrode meets the requirements of supercapacitor fast chargi...
