Abstract

The invention discloses a preparation method of a flexible stretchable miniature supercapacitor, which comprises the following steps of: (1) designing an interdigital electrode pattern by using modeling software; (2) by means of a 3D printer with polylactic acid wires serving as raw materials, printing an interdigital electrode mold,which is composed of a bottom plate and an outer wall, and interdigital electrode patterns formed by protrusions are arranged on the bottom plate; (3) uniformly mixing the silicone rubber and a cross-linking agent, and injecting the mixture into a mold to be cured and formed to form a silicone rubber-based interdigital electrode template, wherein the surface of the template is provided with an interdigital electrode pattern formed by grooves; (4) sequentially depositing a silver current collector, a Bi2O3 / CNT active material and a silver current collector in the groove through a dispensing process to obtain an interdigital electrode; and (5) coating electrolyte on the interdigital part, connecting copper sheets at the two ends of the electrode, and carrying out plastic packaging by using a PET film. The method is simple in process, and the obtained capacitor substrate is light in weight, good in bending performance, high in mechanical stability and suitable for large-scale production.
