Abstract

The invention discloses a self-packaging three-dimensional micro supercapacitor processed by laser and a processing method, and belongs to the field of three-dimensional energy storage electronic devices. Patterning processing is carried out in the mixed electrolyte gel material by utilizing laser, the composite electrode material is generated by utilizing light-induced reduction and carbonization effects, and the whole process is carried out in situ in the mixed gel electrolyte, so that selective conversion from the electrolyte material to the electrode material can be realized; and the prepared patterned internally-carved micro supercapacitor does not need additional electrolyte and other packaging steps. The invention relates to a self-packaging three-dimensional micro supercapacitor processed by laser, which is mainly composed of an electrode processed in a patterning manner, and the appearance of the electrode is a porous shape with tightly crosslinked four surfaces. The three-dimensional thickness regulation and control range of the three-dimensional inner-carved self-packaging supercapacitor covers a millimeter level to a centimeter level. The invention has the advantage of high storage energy, is suitable for large-scale preparation, and is convenient to transport and store.
