Electric double layer capacitor package and method for manufacturing the same

Abstract

An electric double layer capacitor and a manufacturing method thereof are provided. Concretely, lamination of a lower part electrode, a separator, and an upper part electrode is performed sequentially in the bottom housing of a ceramic concave container, in the process of covering the bottom container via a sealing plate, more than one protrusion is formed on the inner bottom of the bottom container. According to the electric double layer capacitor package and the method for manufacturing the same, binder pouring technology can be eliminated, and the lower part electrode and the bottom container, and the upper part electrode and a sealing plate are combined in a firmer way, thereby preventing short circuit and effectively reducing interal resistance.

Description

technical field [0001] The present invention relates to an electric double layer capacitor and a manufacturing method thereof. Specifically, the lower electrode, the separator, and the upper electrode are sequentially laminated in the bottom case of a ceramic concave container, and then formed on the inner bottom surface of the bottom case when the bottom case is covered with a sealing plate. More than one protrusion. Background technique [0002] In electronic products such as information and communication equipment, it is very important to supply stable energy. Generally, this function is realized by a capacitor (Capacitor). That is, capacitors have the function of charging and discharging in the circuits of information communication equipment and various electronic products, thereby stabilizing the circuit current. General capacitors have the characteristics of short charging and discharging time, long life and high output density, but due to their low energy density, t...

Problems solved by technology

[0012] However, according to the prior art, in order to effectively inject the adhesive during the joining process, the probe of the adhesive injecting device should be close to the bottom of the ceramic container while injecting the adhesive in a close distance that cannot be touched. mixture, but as mentioned earlier, it is difficult to control the thickness of the ceramic container within a certain range during the manufacturing process, and the thickness of each ceramic container is different, so there will be friction when injecting the adhesive. When the probe for injecting the adhesive touches the bottom of the ceramic vessel or is too far away from it

When the probe touches the ceramic container, it will not only damage the expensive adhesive injection equipment but also increase its manufacturing cost, and when the probe injects the adhesive at a long distance, it will fail to drip adhesion. agent problem
