How Can Overheating Affect the Performance and Lifespan of Your Battery?
Overheating can significantly reduce your battery’s performance and lifespan by causing chemical damage, increasing internal resistance, and accelerating wear.
Chemical damage occurs when the battery temperature exceeds the optimal range. High temperatures can lead to the breakdown of battery components, particularly in lithium-ion batteries. A study by Zhang et al. (2020) found that sustained exposure to temperatures above 45°C can cause severe degradation of the electrolyte, resulting in reduced capacity.
Increased internal resistance is another effect of overheating. Higher temperatures can create more growth of the solid electrolyte interphase (SEI) layer on the anode, which increases the resistance that the current faces when flowing through the battery. This reduction in efficiency was highlighted in research by Liu et al. (2019), which indicated that for every 10°C increase in temperature, the internal resistance can rise significantly, decreasing the battery’s overall performance.
Accelerated wear happens because heat can cause thermal stress. This stress leads to chemical reactions that would not typically occur at lower temperatures. The aging process of batteries speeds up due to these reactions, diminishing the battery’s capacity faster than expected. Research by Pesaran et al. (2018) shows that excessive heat exposure causes lithium-ion batteries to lose 20-30% of their capacity sooner than if they had been kept within safe temperature limits.
In summary, overheating leads to chemical damage, increased internal resistance, and accelerated wear, posing significant risks to battery performance and longevity.
