Battery Tab<\/a>Pick-up inspection<\/p>\n

Equipment used: gloves, scissors, turntable work clothes, red tape, sample bag<\/p>\n

1. Check the quantity, specifications and models of the goods according to the packaging details and quality inspection certificate<\/p>\n

2. Take samples of 5 products of various specifications and conduct immersion tests on 5 products. Keep records of sample retention and immersion tests.<\/p>\n

3. For the appearance inspection of the tabs, the film surface must be clean and smooth, flat and without creases, bevels, misalignments and burrs; the metal strip surface must be clean and smooth, flat and without creases, oil stains, oxidation, scratches and embossing.<\/p>\n

4. After passing the immersion test and appearance inspection, it will enter the next process and be labeled and put into storage.<\/p>\n

5. Isolate and place unqualified products, promptly report to the headquarters, and keep records of the handling<\/p>\n

6. Keep records of delivery inspection<\/p>\n

Electrolyte immersion resistance test<\/p>\n

Equipment used: gloves, masks, tissues, clamps<\/p>\n

1. After the immersion test, take out the grinding bottle and place it in a dry place to cool naturally to room temperature.<\/p>\n

2. Pour out the electrolyte in the bottle, remove the battery tabs, and wipe them clean with a paper towel.<\/p>\n

3. Use a clamp to tear off the tab film from the metal belt. If the white area of the film attached to the metal belt is 50% and there is no direct penetration on the left and right edges, it is qualified. Otherwise, it is unqualified.<\/p>\n

4. Keep records of immersion tests<\/p>\n

Shipping inspection<\/p>\n

1. Check the quantity and specifications of the goods shipped according to the delivery note<\/p>\n

2. Check whether the label on the carton is correct and meets customer requirements<\/p>\n

3. Confirm whether the warranty and delivery note are packed in the carton<\/p>\n

4. Keep good delivery inspection records<\/p>\n

Return inspection<\/p>\n

1. Re-inspect based on the reason for the customer's return<\/p>\n

2. Determine whether the problem can be corrected, isolate it, promptly report it to the headquarters, and keep records of the handling.<\/p>\n

Electrolyte resistance test<\/p>\n

Test Equipment<\/p>\n

Nitrogen bottle, glove box, ground-mouth bottle, syringe, measuring cup, electrolyte, distilled water, thermostat, basin, water, tweezers, absorbent paper, anti-corrosion gloves, mask<\/p>\n

Test requirements: 1. Make sure the glove box, ground bottle, measuring cup and thermostat are dry before the experiment. 2. Check the equipment inspection records and start the operation after confirming that the equipment is normal. The test results shall be judged according to the "Tag Test Procedure".<\/p>\n

\"\"

Test steps<\/p>\n

1. Turn on the thermostat, set the temperature to 85\u00b0C, and start pre-temperature rise.<\/p>\n

2. Put the pole ear into the ground bottle<\/p>\n

3. Inject a small amount of distilled water into the syringe. Only 4 drops of water are needed for one experiment.<\/p>\n

4. Place the ground-mouth bottle, syringe, and measuring cup into the glove box.<\/p>\n

5. Confirm that the air inlet and outlet valves of the glove box are open. Open the valve of the nitrogen bottle, check whether the air pressure in the nitrogen bottle is normal, and then open the air pressure valve. Start to flush nitrogen into the glove box to remove the air in the box. After about 2 minutes, proceed to the next step.<\/p>\n

6. Pour 15ml of electrolyte into the measuring cup and add 4 drops of distilled water. The water content of the electrolyte is about 2500ppm. Shake the electrolyte in the measuring cup evenly and pour it into the ground-mouth bottle, then cover the bottle cap tightly.<\/p>\n

7. Seal the electrolyte bottle and place it in a corner of the glove box. Then close the nitrogen bottle valve and the air pressure valve.<\/p>\n

8. Quickly put the grinding bottle into the oven, set the temperature to 85\u00b0C, and set the baking time to 240 minutes.<\/p>\n

9. Clean the test equipment and site. Monitor the test situation every hour and keep relevant test records.<\/p>\n

10. Test result determination<\/p>\n

appendix:<\/p>\n

The battery pole ear comprises a pole ear metal strip, one end of which is connected to the pole ear in the packaging bag composed of aluminum-plastic packaging film, and the other end extends to the outside of the packaging bag mouth, a section of the pole ear metal strip at the packaging bag mouth is covered by a thin film polymer composite material, and a layer of liquid adhesive is also applied at the intersection of the rod metal strip and the covered polymer composite material and the packaging bag. The adhesive can be applied outside the packaging bag mouth, inside the packaging bag, or inside and outside the packaging bag, and the liquid adhesive forms a cured film after curing. The utility model adds a glue coating process without changing the processing technology of the existing battery and its battery core, effectively seals the battery electrolysis containing corrosive substances in the aluminum-plastic packaging film bag, ensures the sealing of the pole ear, and is also suitable for the same packaging method of other types of chemical batteries.<\/p>","protected":false},"excerpt":{"rendered":"
