Safety valve and pressure relief device production material - aluminum alloy

In the design and manufacture of EPS (encapsulated power System) batteries, safety valves and pressure relief devices are important components to ensure the safety performance of the battery. Aluminum alloys are getting more and more attention in the manufacture of these components due to their unique properties. The following details the application of aluminum alloy in the safety valve and pressure relief device of EPS battery cell.

main content

summarize

Aluminum alloy is an alloy material with aluminum as its main component and other metal elements (such as copper, zinc, magnesium, silicon, etc.) added to enhance its strength and other properties. Aluminum alloy not only has good mechanical properties, but also because of its light weight, high strength and good processing properties, it is widely used in aerospace, automotive, construction and battery technology.

advantage

Lightweight: The lower density of aluminum alloy makes the safety valve and pressure release device lighter at the same strength, helping to reduce the weight of the entire battery, thereby improving energy density and endurance.

Excellent corrosion resistance: The surface of aluminum alloy naturally forms a layer of aluminum oxide film, which can effectively resist oxidation and corrosion, and is suitable for the chemical environment inside the battery.

Good strength and toughness: high-strength aluminum alloys (such as 7075 alloy) can provide good toughness and improve safety while meeting pressure requirements.

Excellent thermal conductivity: Aluminum alloy has good thermal conductivity, which helps the battery to dissipate heat generated during operation and prevent safety hazards caused by overheating.

Easy to process: Aluminum alloys are easy to cast, extrude, press and weld, making the production of complex shapes of safety valves and pressure relief devices more flexible.

Specific applications in EPS batteries

Safety valve structure: Safety valve is usually made of aluminum alloy, including valve body, seat, spring and seal parts. The design needs to consider the opening pressure and sealing performance of the valve to prevent gas leakage.

Pressure release characteristics: The safety valve made of aluminum alloy can be opened quickly when the specific internal pressure is reached, effectively preventing the danger caused by excessive internal pressure. The flexibility and reliability of this valve design makes aluminum alloy an ideal material.

Reduce overall weight: Due to the low density of aluminum alloy, the use of safety valves made of aluminum alloy can significantly reduce the overall weight of the battery and improve the energy density of the battery, especially in electric vehicles and portable electronic devices is crucial.

Commonly used aluminum alloy materials

In the manufacture of EPS battery safety valves and pressure relief devices, different types of aluminum alloy materials can be selected:

6061 aluminum alloy: 6061 alloy with its excellent mechanical properties and good corrosion resistance and widely used, suitable for high strength requirements of the safety valve design.

7075 Aluminum alloy: 7075 alloy is a high-strength aluminum alloy, ideal for use as a valve component to withstand higher pressures.

4045 aluminum alloy: This aluminum alloy is often used in the production of composite materials, has good weldability and corrosion resistance, and is suitable for specific design needs.

Aluminum alloy safety valve design considerations

Opening pressure: The design should determine the appropriate opening pressure, so that when the internal pressure of the battery is too high, it can be released in time, so as to avoid explosion or other safety accidents.

Structural design: The thickness, shape and other design factors of the aluminum alloy must ensure that it does not deform under predetermined conditions and has good sealing performance.

Surface treatment: The surface treatment of aluminum alloy (such as anodizing, spraying, etc.) can not only improve its corrosion resistance, but also improve its aesthetic and wear resistance.

CONCLUSION

Because of its unique light weight, high strength and good corrosion resistance, aluminum alloy has become the ideal material for EPS cell safety valves and pressure relief devices. Through reasonable design and manufacture, the safety valve of aluminum alloy can effectively ensure the safety and reliability of the battery.ainless steel materials will continue to increase, promoting the safety and reliability of the battery industry.
