How to repair a blown polymer lithium battery?

How to repair a blown polymer lithium battery? 1. Preparations Find a ventilated place, prepare the polymer lithium battery, scissors, bill holder, toothpicks, 705 translucent silicone rubber, translucent tape, syringe, infusion needle with a plastic tube (must be the smallest size) ); 2. Pumping and preparing to connect the syringe with the infusion needle, hold the needle in a suitable position at the lithium battery seal, and then fix the needle with tape to keep it from shifting, use a toothpick to take a small amount of 705 silicone rubber and apply it to the needle Nearby, beware of air leaks. 3. Extracting gas Pull the syringe to extract the gas from the battery. After filling a tube, clamp the plastic tube of the needle with a bill holder, separate the syringe from the needle, discharge the gas, and then connect the syringe to the needle and repeat the operation. 4. Sealing After many operations, the aluminum encapsulation film of the battery will gradually tighten and close to the battery body, and the battery will become very hard. When the gas cannot be pumped out and the battery is close to the vacuum state, clamp the plastic tube behind the needle with a clip, cut a small piece (1cm square) of translucent tape with scissors, stick it to the needle hole, press it and set the needle, and the operation is complete. 5. Quality inspection Because the pinhole is very small and sealed with silicone rubber and translucent tape, gas will not enter the battery anymore. After a few hours after the silicone rubber is cured, the lithium battery is detected, and the lithium battery is fully charged and discharged several times with a relatively small current. If the problem of outgassing no longer occurs, the solution is completed. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
