specific Embodiment 1

[0028] In this embodiment, the supercapacitor element is that the electrode core is packaged in a liquid-tight and air-tight capacitor casing, the capacitor casing is a hard casing, and the hard casing is made of metal or plastic such as aluminum, steel, and tinplate; The hard shell is provided with a liquid injection port communicating with the outside for injecting electrolyte.

[0029] After the capacitor element is prepared, it is vacuum impregnated, the steps are:

[0030] Step 1. Pack the supercapacitor element to be processed into a closed vacuum impregnation tank;

[0031] Step 2, by setting and starting the vacuum pump group, the vacuum degree in the vacuum impregnation tank is reduced to below 10 Pa;

[0032] Step 3, inject filling gas into the vacuum impregnation tank so that the air pressure in the vacuum impregnation tank reaches an atmospheric pressure, and the filling gas is an inert gas;

[0033] Step 4, heating the vacuum impregnation tank so that the ambien...

Abstract

The invention discloses a super capacitor vacuum dipping method comprising the following steps: 1, packing a to-be processed super capacitor element in a sealed vacuum dipping tank; 2, reducing a degree of vacuum in the vacuum dipping tank to be below 10Pa; 3, injecting an inert gas in the vacuum dipping tank to reach one atmospheric pressure; 4, heating the vacuum dipping tank to 130-140 DEG C; 5, starting a vacuum pump set so as to reduce the vacuum degree in the vacuum dipping tank to be below 10 Pa; 6, keeping vacuum-pumping, heating and injecting an electrolyte, and dipping for 8-12 hours; 7, stop vacuum-pumping and heating, filling the filling gas of one atmospheric pressure in the vacuum dipping tank, and opening the vacuum dipping tank and removing the dipped super capacitor element when the temperature drops to 40 DEG C; 8, completely sealing a capacitor housing. The method and device can prevent secondary exposure of an electrode core in the air in a super capacitor manufacture process, and can solve the complex operation and long flow problems.

Description

technical field [0001] The invention relates to a vacuum impregnation method and device for a supercapacitor, belonging to the technical field of capacitor manufacturing. Background technique [0002] Chinese patent document CN 102543481 B discloses a method for manufacturing a supercapacitor. The supercapacitor is composed of an electrode core, an electrolyte and a casing; the manufacturing method is to obtain the electrode core by winding it, and then vacuum-dry it at 100-150°C for 8-72 hour, the electrode core was impregnated with an organic electrolyte under vacuum conditions, and then energized for 10 hours at 50°C with an external 2.7 V DC voltage, and finally packaged in a circular aluminum shell to obtain a supercapacitor product. The disadvantage of this method is that only the electrode core is subjected to vacuum drying and vacuum impregnation. After the vacuum treatment is completed, it needs to be energized under direct current for 10 hours. At this time, the el...
