Embodiment Construction

[0011] Please refer to shown in Fig. 1, below in conjunction with embodiment description a kind of short circuit, open circuit test method of polymer flexible packaging provided by the present invention, its technological process: first prepare a short circuit, open circuit tester 1, then to this instrument 1 a The input end is modified, that is, two lines with positive and negative button switches 2 and 3 are connected in parallel on the input end, one line corresponds to the positive ear 4 of the battery, and the other line corresponds to the negative ear 5 of the battery.

[0012] Next, connect the other output end of the detection instrument 1 to one end of the composite switch, and the other end of the composite switch is connected to a needle-shaped conductor connector 7 .

[0013] If it is detected whether there is a short circuit between the positive electrode ear 4 and the aluminum-plastic film 6 welded on the positive electrode sheet, first close the positive electrod...

Abstract

The invention discloses a short open circuit test method to the polymer flexible packaging, the technical process is that: firstly a general short open circuit detector is prepared, one of the output ends in the detector is modified, namely, the output end is connected with two circuitries with anode and cathode switches in parallel, each circuitry is corresponding to an anode ear and a cathode ear of the batteries, another output end of the detector is connected with a needle shape conductor joint through a composite switch. The detection method is that: firstly each end of two parallel circuitries is correspondingly connected on the anode and the cathode of the batteries, the battery is detected whether is short circuit between the anode and the cathode, afterward the anode circuitry or the cathode circuitry is opened, another needle shape end is pricked into the redundant edge aluminum plastic film to detect whether the anode and the cathode and the plastic film form a short circuit. Adopting the short circuit test method, the batteries liquid leakage and bulge phenomena resulted form the 'box cancer' are avoided, therefore, the reliability of the battery quality is effectively guaranteed.

Description

【Technical field】 [0001] The invention relates to a short-circuit and open-circuit test method, and specifically refers to a short-circuit and open-circuit test method for a polymer flexible package. 【Background technique】 [0002] In the prior art, polymer flexible packaging includes positive and negative plates, a separator placed between the positive and negative plates, tabs welded on the positive and negative plates, and an aluminum-plastic film welded between the positive and negative plates and the tabs . During the processing, due to the special structure of the diaphragm of the outer layer of the flexible packaging or the polymer battery, the positive and negative tabs are easy to contact with the aluminum layer between the aluminum-plastic film of the outer packaging during the battery manufacturing process to form a short circuit. After the battery is charged, the aluminum in the aluminum-plastic film becomes a charged terminal. Through the reaction with the elec...
