Information

With the development of science and technology, the society is paying more and more attention to environmental protection, and the demand for green energy is becoming more and more urgent. Therefore, the use of lithium batteries is also expanding, especially in the new energy automobile industry.

 

If the seal is not in place and the electrolyte leaks and causes a short circuit, it will cause a safety accident of the battery, and a failure of the insulation index will also cause a safety accident.

 

 

This puts forward higher safety requirements for battery products, and the plastic insulating material sealing diagram in the battery explosion-proof cap mainly plays a role of sealing and insulation.

 

In order to improve the safety factor of lithium battery, the solution of explosion-proof cap is generally adopted at present. Lithium-ion battery explosion-proof cap: including upper cap, explosion-proof membrane, orifice plate and sealing ring. The explosion-proof cap must meet the following requirements to ensure its effectiveness.

1. The sealing is smooth and tight, with uniform rubber edges, no wrinkles and not easy to deform.

2. Make sure to pass the blue dot and salt spray test.

3. The internal resistance is stable and controlled within 5mΩ. Sealing ring made of plastic insulating material without leakage

4. It has explosion-proof function.

5. No wrinkles, glue leakage, corrosion, liquid leakage, etc. Products are environmentally friendly and comply with ROHS standards.

 

Generally, the inner sealing ring of the traditional explosion-proof cap is made of polypropylene material, at most it is used on 18650 (a kind of lithium battery). Due to the vigorous development of new energy vehicles, shortening the charging time, increasing the battery capacity, and improving the endurance of the battery have brought unprecedented challenges to the service life of the battery! And the fast charge and high capacity bring about the rapid increase in battery temperature and greatly shorten it. Battery life!
