· At low temperatures, electrolyte ion mobility decreases and electrode reactions slow down. This raises internal resistance (IR) and reduces current output for a given voltage. . Lithium-ion batteries perform best around room temperature. In this article, we explain why temperature extremes impact discharge behavior. . The results show that the battery capacity decreases by 15% compared to the value measured at room temperature when the operating temperature drops to approximately −10 °C, and by 35% at approximately −20 °C. Moreover, prolonged exposure to such conditions accelerates battery degradation, ultimately reducing its lifespan. The problem arises when this single advantage is extrapolated into a blanket safety. .
