Technical parameters：

Application case

Experiment preparation

Material preparation: Prepare an appropriate amount of assembled soft-pack lithium battery semi-finished products, including the batteries that have completed the assembly of positive and negative electrode sheets, electrolyte injection, and initial packaging.

Tools: In addition to the secondary vacuum final sealing machine, prepare auxiliary tools such as scissors, ruler, and gloves.

Environment preparation: Ensure that the operation area is clean and dust-free, and that the temperature and humidity meet the technical requirements to avoid the impact of static electricity and dust.

Experimental procedure

Battery pretreatment: Place the assembled soft-pack lithium battery semi-finished product on the operating table to check whether there is leakage or other defects.

Initial seal inspection: Confirm the initial packaging effect of the battery, ensure that the aluminum plastic film and the battery body fit well, no bubbles and leakage seal phenomenon.

Secondary vacuum final seal:

Place the battery in the working room of the secondary vacuum final sealing machine and close the studio door.

Start the vacuum pump, gradually vacuum to the set value (usually about 10^-2 Pa), keep for a period of time to completely remove the gas and water inside the battery.

Start the heating system, set the appropriate heating temperature and time according to the battery specifications, so that the aluminum-plastic film reaches the molten state.

Activate the sealing device to seal the edge of the battery. Ensure that the sealing line is continuous, smooth and free of bubbles.

After the sealing is completed, the vacuum is slowly released to restore the normal pressure environment.

Open the studio door and remove the encapsulated battery.

Quality inspection: Carefully check each piece of packaged soft pack lithium battery to ensure that the sealing line has no leakage seal, no bubbles, no burning and other undesirable phenomena.

Performance test: Random sampling of some samples for charge and discharge cycle test, evaluate the battery capacity retention rate, internal resistance and other key indicators.

Result analysis

By using a secondary vacuum final sealing machine, the company achieved the following results in the packaging process of soft-pack lithium batteries:

Improve the sealing quality: The final sealing operation in the vacuum environment effectively eliminates the gas and water inside the battery, ensuring the purity of the battery inside and enhancing the sealing.

Reduce internal resistance: The high-quality package reduces the contact resistance between the electrolyte and the electrode material, improving the efficiency of the battery charge and discharge.

Improve safety: Good sealing effectively prevents the external environment from contaminating the battery, reduces the risk of short circuit and leakage, and improves the safety of the battery.

Enhanced product consistency: Standardized operating processes and high-precision equipment ensure that the packaging effect of each battery is consistent, improving the overall quality of the product.
