During use, during use, due to excessive charging current, excessive charge, it will cause battery drums. If you continue to use, you will not only heat, bulge, causing safety hazards, but will speed up battery damage, so internal gas must be accelerated. After removing it, you can continue to use, let you introduce the maintenance method of polymer lithium battery.
The polymer battery is one of a lithium ion battery, but has a number of significant advantages such as high energy density, smaller, ultra-thin, light weight, and high safety than liquid lithium batteries. It is a new type of battery. In shape, the lithium polymer battery has ultra-thin characteristics, which can be used in combination with various products, making a battery in any shape and capacity.
The battery can achieve a minimum thickness of 0.5mm. Its nominal voltage is also a nominal voltage 3.
7V as Li-ION, no memory effect. Common polymer lithium battery pack drums repair skills, ready to work, find a ventilated location, ready to treat polymer lithium battery pack, scissors, bills, toothpick, 705 transparent silicone rubber, transparent tape, syringe, with a plastic The infusion needle (must be the least amount); Second, the angility is ready to connect the syringe and the infusion needle, and the hand hold the needle to find a suitable position at the sealing of the lithium battery pack, then secure the needle with tape. , Use a teeth sign to take a small amount of 705 silicone rubber to apply near the needle to 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 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 in a few hours, the lithium battery pack is tested, first charge and discharge with a smaller current, such as no intake, 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.
What is the cause of the polymer lithium battery pack drum? 1 The phenomenon of the polymer lithium battery cells does not have to be drumped, since the air is electrically conductive, and therefore, the time is too long, which is equivalent to direct contact with the positive and negative electrode of the battery, and performs chronic short circuit. 4, the reason why the quality of lithium battery charger is poor. The charger uses inferior sheet, refurbished or low parameter device, fever, parameter drift is not accurate, so that the charging voltage is out of control, resulting in the internal gas extrusion of the lithium battery results in deformation of the battery case and even explosion.
5, the charging time is too long. If overcharge can result in a large amount of gas flush electrode plate, resulting in a lithium battery pack to fall off, shorten battery life, so that the battery's loss of water is accelerated, affecting the decomposition of the electrolyte, so that the battery temperature increases, so that the drum! The maintenance method of the polymer lithium battery pack drum bag, generally polymer soft bag battery over charge will "drum", if the steel shell battery will explode. Lithium batteries may explode in the case of leakage or damage, it is recommended not to use the battery again, replace the battery.
