Manufacturing method of capacitor |
摘要 |
<p>There is provided a manufacturing method of a capacitor including: providing the capacitor having positive and negative polarizable electrodes which generates an electric double layer; a separator with which the polarizable electrodes are electrically insulated therebetween; and collecting electrodes that are made of metal and lead out charges from the polarizable electrodes, and joining a bundle of lead portions of the collecting electrodes to an electrode terminal by ultrasonic welding. A gross area of protruding portions in an ultrasonic-welding surface is made to be within a range of 5 to 50% of a contact area of the ultrasonic-welding surface and lead sections of collecting electrodes. The manufacturing method can perform junction of electrode terminals without increasing junction resistance only by ultrasonic welding even if the bundle of lead portions of collecting electrodes is thick, or the number of sheets of collecting electrodes is large.</p> |
