Embodiment Construction
[0026] figure 1 It is a schematic diagram of the manufacturing process of a capacitor according to an embodiment of the present invention. Please refer to figure 1 , firstly, step S100 is performed to provide a porous substrate 100 . The porous substrate 100 has a large number of pores and therefore has a high specific surface area. The material of the porous substrate 100 is, for example, melamine, polystyrene, polyurethane, polyethylene, ethylene-vinyl acetate copolymer, thermoplastic rubber, polyvinyl chloride or other polymers.
[0027] In one embodiment, the porous substrate 100 may be selectively cleaned. Acetone or other cleaning solutions may be used to clean the porous substrate 100 to remove impurities on the surface of the porous substrate 100 and in the pores. However, the present invention is not limited thereto, and the porous substrate 100 may also be subjected to common cleaning treatment to remove impurities on the surface of the porous substrate 100 and i...

Abstract
The invention provides a capacitor and a manufacturing method thereof. The capacitor comprises a porous substrate, electrolyte composition and a pair of electrodes, wherein the porous substrate has multiple holes, the electrolyte composition is in the holes of the porous substrate, the electrolyte composition comprises an electrolyte and a nanometer carbon material dispersed in the electrolyte, and the electrodes are respectively arranged at two opposite surfaces of the porous substrate. According to the capacitor, the porous substrate and the nanometer carbon material have high porousness and high specific surface areas, so the large-amount electrolyte can be absorbed, charge storage capacity of the capacitor can be effectively improved, moreover, the electrolyte composition can be effectively absorbed by the porous substrate on a surface of the porous substrate and the holes, a leakage problem of the capacitor can be avoided, the capacitor is simple to manufacture and can be manufactured without other complex equipment, and manufacturing cost is low.
Description
technical field [0001] The invention relates to a capacitor and a manufacturing method thereof, in particular to a capacitor with a porous substrate and an electrolyte composition and a manufacturing method thereof. Background technique [0002] Capacitors have the ability to store energy, so they are widely used in electronic products. According to different dielectric materials, capacitors can be divided into liquid capacitors and solid capacitors. The dielectric material of solid capacitors is generally conductive polymer, while the dielectric material of liquid capacitors is generally electrolyte. [0003] Under long-term use of liquid capacitors, the electrolyte in the capacitor will expand due to overheating, which will easily cause the capacitor to rupture and cause liquid leakage, and even cause explosions due to the temperature exceeding the boiling point of the electrolyte. Contents of the invention [0004] The invention provides a capacitor with a porous subst...
