1060 aluminum plate for power battery cap

The power battery cap is a component on the top of the power battery. It is an important component of the power battery. It can protect the safety of the power battery and has the characteristics of overpressure, explosion-proof and overcurrent protection. However, many people are not clear about the role of the power battery cap. Here we will explain the role of the power battery cap for you:

1. Overcharge protection function

Power batteries using different positive electrode materials and electrolytes have different temperature and voltage change curves when overcharged. Since the power battery cap has an overcharge protection function, when the overcharge reaches a certain level, the charging will be forced to terminate. At this time, if the internal temperature of the power battery has reached a thermal runaway state, the internal pressure continues to rise, the explosion-proof membrane of the power battery cap will be broken, and the substances in the power battery will be ejected with high-pressure gas.
2. Protect the power battery when the battery is short-circuited

There is a PTC protection element inside the ordinary cylindrical lithium battery cap. Its working principle is mainly that when a certain temperature is reached, its internal structure changes, and the resistance increases significantly, so as to prevent the battery from discharging, and it has the function of protecting the battery when the battery is short-circuited externally.
3. Lower internal resistance
The power battery cap adopts relevant laser welding, ultrasonic welding and other technologies, as well as material selection experience, to achieve an internal resistance of less than 0.5 milliohms (between the rivet surface and the lead).
4. Ensure the safety performance of power batteries

Each specification of the power battery cap is assembled by laser spot welding or hot pressing and wrapping from its own parts. It is made of aluminum, which further improves the stability of the explosion-proof system. When the internal pressure of the power battery reaches the specified explosion specification range, a large amount of material in the power battery is quickly discharged through the pressure relief hole on the top cover, ensuring the safety performance of the power battery.

Aluminum plate for power battery cap (explosion-proof valve)

Power battery cap can use 1060-o aluminum strip to prevent the battery from continuing to charge after being fully charged, reducing the occurrence of battery explosion. The thickness of 1060 aluminum strip used for explosion-proof valve is generally 0.3-0.5mm. The width is 14mm, 22mm, and 25mm. Henan Mingtai Aluminum has successfully tested it and supplied it to manufacturers with good performance and reached a cooperative relationship.
