Polymer lithium battery production to pay attention to the place.

1. Stop Lithium battery is short-circuited to prevent the battery from short-circuiting. A short circuit will generate a large current, which then heats the lithium battery and leaks electrolyte. It is very dangerous to produce corrosive gas or explode. When the pole piece is connected to the surface of a conductive object, it is easy to short-circuit. An external short circuit will cause heating and damage to the lithium battery. An appropriate maintenance circuit can be selected to maintain the lithium battery in the event of an accidental short circuit.

2. Mechanical shocks, drops, bumps, twists, etc. may reduce the function of the lithium battery.

3. Matters needing attention in rod operation: The mechanical strength of rod parts is not very strong, especially aluminum parts. When unnecessary, do not bend the rods. 4. Precautions for battery shell planning: shell resistance The battery shell should have satisfactory mechanical strength to prevent the battery from being mechanically impacted. When fixing the battery, the side with the largest area of the battery should be fixed on the external charger, and the paste should be strong. Do not loosen behind the battery unit.

4. The internal planning of the housing-the battery device must not have sharp edges in the housing, and the battery pack must not be perforated.

5. Pole piece connection (try not to do this operation, and be careful not to short-circuit D. It is recommended to use ultrasonic or spot welding methods: the housing should be designed to protect the pole pieces from external forces. If you use manual welding to maintain the board, the following precautions are very important to ensure the battery function important:

The welding temperature of ferrochrome must be controllable and anti-static: the temperature of ferrochrome must not exceed 350C during welding; the welding time must not exceed 3 seconds; the number of welding must not exceed 5 times, and the next welding can be performed after the pole pieces are cooled: direct heating of the welding is strictly prohibited Core, higher than s0c will damage the battery.

6. In the event of an accident (the battery has a damaged outer packaging and cannot be used in the case of liquid leakage), the external charging plan should take into account that even if the battery leaks, it will not heat up, and the test will take the maintenance circuit away from the leaking electrolyte.

Prevent short-distance circuits exposed to different voltages, including around plugs. There should be no liquid from the electrolyte in the battery, but once the electrolyte overflows and contacts the exposed circuit, the high-potential terminal material may dissolve and precipitate to the low-potential terminal, and then cause a short circuit. The planning of the maintenance board must cover a maintenance layer. Pay attention to the battery assembly matters when assembling the battery, do not allow bumps, high temperatures or contact with sharp parts, and do not allow short circuits. When assembling, no open flame is allowed to connect with other batteries.
