6 FAQs about [New energy battery shell damage]

Do overcharged batteries increase the flame area after thermal runaway?

The flame area of medium overcharged> high-level overcharged> low-level overcharged batteries and the flame area of thermal runaway increased by 22213.95 cm 2 compared to the maximum of 100 % SOC, and the flame propagation speed of the batteries after thermal runaway showed that the greater the SOC, the stronger the intensity of the flame.

Are new energy vehicle batteries bad for the environment?

Every year, many waste batteries are thrown away without treatment, which is damaging to the environment. The commonly used new energy vehicle batteries are lithium cobalt acid battery, lithium iron phosphate (LIP) battery, NiMH battery, and ternary lithium battery.

How to protect a battery from thermal runaway damage?

At the cell level, without compromising the fundamental performance of the battery, incorporating flame retardants into the battery electrolyte and opting for SEI films that are more heat-resistant are both effective strategies for minimizing the severity of thermal runaway damage.

What happens if a battery breaks a weak link?

During the breaking process of the weak link, an arc re-breakdown will be generated as the battery voltage rises. The higher the battery current, the greater the energy of the arc, leading to the immediate vaporization of the surrounding metal and causing significant damage to the battery.

What happens if a battery catches fire?

In a short time, the two affected batteries caught fire first, and the maximum temperature during the runaway of the battery could reach over 800 °C, far exceeding the battery’s TR control threshold. This led to internal damage to the battery and the ejection of high-temperature substances.

What happens if a battery overcharges?

As the degree of overcharging exceeds 120 % SOC the chemical reaction inside the battery intensifies and heat accumulates, the maximum surface temperature of the battery during the charging process undergoes a significant increase to 66.1°C, which is 102 % higher compared to 32.7°C at 100 % SOC.
