How to repair polymer lithium ion batteries

The polymer lithium battery is in the process of use, because the charging current is too large, overcharge, etc. can cause the battery drum bag, and there is a low-cost drum (lifting) polymer lithium battery on the shopping online, and the polymerization of the internally occurring Lithium battery, if you continue to use, you will not only heat, bulge, causing safety hazards, but accelerate battery damage, so you must continue to use the internal gas can continue to use, and give you a simple removal of the internal gas of the polymer lithium battery. method.

First, prepare to work: find a ventilated location, ready to be treated, polymer battery, scissors, bill, toothpick, 705 transparent silicone rubber, transparent tape, syringe, infusion needle with a plastic tube (must be the least small) II. III: Pumping Preparation: Connect the syringe and the infusion needle, hand-held needle to find a suitable position at the lithium battery seal, then keep the needle with the tape to keep the needle without displacement, with a teeth, a small amount of 705 silicone rubber coated Near needle, prevent leakage. Third, extracting the gas: pull the syringe to extract the gas in the battery, after the tube is filled, the needle is separated with the needle, separating the syringe and the needle, discharging the gas (although the gas in the battery is very difficult So find a ventilated location), then connect the syringe with the needle, repeatedly.

Fourth, sealed: After multiple operations, the packaging aluminum membrane of the battery will gradually tighten and close to the battery body, the battery will become very hard. After the gas cannot be extracted, after the inside of the battery is close to the vacuum, the plastic tube after the needle is clamped, cut a small piece with a scissors (1cm square) transparent tape, attach the needle, press the needle (and our usual infusion The same is the same as the needle). V.

Quality inspection: Since the pinhole is very small, there is silicone rubber and transparent tape seal, and the gas will not enter the battery. After a few hours, after the silicone rubber is cured, the battery is tested, 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 generation, you can follow the above flow, then operate once, if it is still unable to solve, the battery has been scrapped.

I have purchased more than ten of the 10-cost polymer lithium batteries purchased on the shopping online. After the above treatment, it has returned to normal use, the effect is very good.
