Drying method and drying device for supercapacitor

Abstract

The invention relates to the capacitor manufacture field, and is to provide a drying method and drying device for a supercapacitor. The drying method for the supercapacitor comprises the following steps: (1) putting the supercapacitor to a drying chamber arranged in a drying furnace; (2) extracting the air in the drying chamber until the vacuum degree is lower than 1 pa; (3) filling nitrogen to the drying chamber; (4) heating the drying furnace for 2-5 hours until the temperature reaches 120-200 DEG; (5) extracting the nitrogen in the drying chamber until the vacuum degree is lower than 1 pa; (6) keeping the vacuum degree in the drying chamber to be lower than 1 pa, and meanwhile, holding the temperature of the drying furnace to be 120-200 DEG for 5-10 hours and performing drying; and (7) filling the nitrogen into the drying chamber, opening the drying furnace and the drying chamber, and taking out the supercapacitor which has been dried. The drying efficiency of the drying method for the supercapacitor is high; the drying effect is good without influencing the service life; and the drying device of the drying method for the supercapacitor is simple in structure and is capable of satisfying the drying requirements.

Description

technical field [0001] The invention relates to the field of capacitor manufacturing, in particular to a supercapacitor drying method and a drying device. Background technique [0002] Supercapacitor, also known as electric double layer capacitor, is a new type of energy storage device, which has the characteristics of short charging time, long service life, good temperature characteristics, energy saving and environmental protection. The invention of Chinese patent application number 201210140580.5 relates to a high-performance supercapacitor and its manufacturing process. The supercapacitor consists of an electrode core, an electrolyte and a casing. The manufacturing process welds the positive and negative tabs of the prepared electrode cores to the positive and negative terminals, then puts the electrode cores at the welded terminals into the shell, and then puts the shell with the electrode cores in the vacuum Carry out vacuum drying in a drying oven, and finally vacuum...
