Polymer lithium ion battery pack drum repair skills, ready to work, find a ventilated location, ready to treat polymer lithium ion battery pack, scissors, bill clips, toothpick, 705 transparent silicone rubber, transparent tape, syringe, The infusion needle of the plastic tube (must be the least amount); Second, the angle is ready to connect the syringe and the infusion needle, and the handheld needle is looking at a suitable position at the lithium-ion battery pack, then keep the needle with the tape fixed needle Displacement, use a small amount of 705 silicone rubber with a teeth to apply near the needle, prevent leakage. Third, extracting the gas pulls the syringe to extract the gas in the battery, after a tube, sandwich the needle of the needle with the bill, separated the syringe and the needle, discharge the gas (although the gas in the battery is not toxic, but the taste is hard, So find a ventilated location), then connect the syringe with the needle, repeatedly. Fourth, the seal has been repeatedly operated, and the packaging aluminum film of the battery will gradually tighten and close to the battery body, and the polymer lithium ion battery pack will become very hard.

After the gas cannot be extracted, the internal portion is close to the vacuum, and the plastic tube after the needle is sandwiched, cut a small piece (1cm square) with a scissors, and attach the needle, press the needle, and the operation is completed. V. Quality check due to very small pinhole, silicone rubber and transparent tape seal, gas will not enter the battery.

After the silicone rubber is cured for silicate, the lithium ion battery pack is detected, first charge and discharge with a smaller current, if there is no relatively intuitive problem, that is, the processing is completed. If there is still a gas, you can follow the above procedures, then operate once, if it is still unable to solve, the battery has been scrapped. I have purchased more than ten drum-free lithium-ion batteries in the shopping online, and after the above treatment, it has returned to normal use, and the effect is very good.
