As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects.
The optimal temperature range for most lithium-ion batteries is typically between 20°C to 25°C (68°F to 77°F). Operating within this range helps maintain a balance between performance and longevity. Manufacturers often integrate thermal management systems into their devices or electric vehicles to regulate the battery temperature.
Conversely, high temperatures accelerate the chemical reactions within a lithium-ion battery, which can result in faster aging and a shorter overall lifespan. In very hot conditions, there is a risk of thermal runaway, where the battery's temperature increases uncontrollably, posing safety hazards.
In cold climates, lithium batteries can experience reduced capacity and power output due to a phenomenon called “cold cycling.” The electrolyte in the battery can become more viscous at low temperatures, impeding ion flow and limiting the battery's ability to deliver energy.
For example, lead-acid batteries tend to experience a decline in voltage output as temperatures decrease. On the other hand, lithium-ion batteries are known to perform better in colder temperatures compared to lead-acid batteries as their voltage output decreases at a slower rate.
For example, lithium-ion batteries have a more significant change in voltage compared to alkaline batteries when exposed to different temperatures. In addition to the correlation between temperature and voltage, it is crucial to consider the temperature limits within which a battery operates optimally.
