Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific embodiments, but the protection scope of the present invention is not limited to the following embodiments.

[0025] A method for manufacturing the positive and negative conductive sheets of a battery or capacitor, including three steps of spot welding, seam welding, and adhesive tape, in which the positive and negative plates and the conductive sheets are firstly positioned by spot welding and then fixed by seam welding Connect, then insulate with tape.

[0026] The specific steps are:

[0027] 1. Spot welding of positive and negative plates

[0028] (1) Turn on the spot welder and adjust the voltage to the value of pulse voltage 100-500V, so that the voltage can be adjusted within the range of 2-3 gears.

[0029] (2) Align the conductive sheet with the right side of the trimmed plate, and evenly spot-weld 6 to 10 points at the overlap between the conductive sheet and the electrode pla...

Abstract

The invention relates to a manufacturing method of an anode conducting strip and a cathode conducting strip of a battery or a capacitor, which comprises three steps of spot welding, roll welding and pasting an adhesive tape. The anode conducting strip and the cathode conducting strip can be positioned by spot welding, then connected by roll welding and fixing, and performed an insulation treatment by the adhesive tape. Compared with the spot welding process, the welding process of first spot welding then roll welding is capable of increasing the contact area of the conducting strip and a pole plate, tightly connecting the pole plate and the conducting strip, reducing the internal resistance, raising the conductivity, raising the effect of high power charge and discharge of the pole plate and enhancing the capability of ultra-high multiplying power rapid charge and discharge of the products.

Description

technical field [0001] The invention belongs to the field of batteries or capacitors, in particular to a method for manufacturing positive and negative conductive sheets of batteries or capacitors. Background technique [0002] With the gradual advancement of the country's new energy construction, the research on new energy has entered a rapid development track, especially the research on supercapacitors has attracted the attention of various countries. The traditional current-collecting method of the positive and negative plate conductive sheets (tabs) generally adopts a single-piece spot-welded conductive sheet and a whole group of conductive sheets with bolts. This method can only meet the general requirements of high-rate charge and discharge of the battery, and cannot solve the problem. Key issues such as ultra-high rate and high current charging and discharging, high current start-up and operation of various equipment. [0003] By searching, no published patent docume...
