What is the temperature of a lithium ion battery?
As figure shows, the temperature of lithium-ion battery rapidly rose after the short circuit starting, and the temperature reached 110 °C in a short period. Then, due to the triggering of PTC and CID components, the temperature began to enter a stable period. The temperature was maintained at about 110 °C.
What happens if a lithium ion battery is short-circuited externally?
As a result, when the lithium-ion battery was short-circuited externally, the battery temperature rose rapidly to the maximum temperature that the battery can rise. The highest temperature caused by external short circuit appeared in the case of a single battery. The higher the SOC, the faster the battery temperature rose.
What causes the highest temperature caused by an external short circuit?
The highest temperature caused by external short circuit appeared in the case of a single battery. The higher the SOC, the faster the battery temperature rose. In the cycle charge and discharge, the rate of decay of the battery after an external short circuit was twice faster than that of a normal battery.
Are lithium-ion batteries prone to thermal runaway during an inter-NAL short circuit?
They found that the risk of thermal runaway during an inter-nal short circuit increases as the battery’s state of charge (SOC) increases. Wu et al. explored the relationship between the electrochemical characteristics and thermal stability of advanced lithium-ion batteries in abuse testing .
What happens if a lithium battery reaches 90 °C?
Once the temperature of LiBs surpasses 90 °C, the exothermic chemical reactions within the battery accelerate, initiating a positive feedback loop of increased heat generation. The escalating temperature can lead to thermal runaway, ultimately resulting in fires and explosions [2, 3].
How does temperature affect a lithium ion battery?
Temperature of lithium-ion battery starts to increases. At the second stage, the discharging current decreases slowly. Voltage of battery increases and becomes stable slowly. These two stages are the same to other studies. At the third stage, the resistance of PTC increases after its temperature increase.
