Reducing charging times and increasing vehicle range are desirable for better battery performance and lifespan. One of the main challenges associated with fast charging and discharging is the degradation of the battery’s electrodes, resulting in decreased battery capacity and increased internal resistance.
Fast charging is normally accompanied by high heat generation rates and significant inhomogeneities. At the same time, high charging currents applied at low temperatures may be detrimental to battery lifetime and safety. As such, effective and flexible thermal management strategies are critical to enabling fast charging in all conditions.
Traditional fast charging methods usually entail charging the battery with high currents. Nonetheless, prolonged high-current constant charging can cause a progressive rise in battery temperatures. Excessive temperature can shorten the lifespan of LIBs, leading to decreased battery performance and driving range .
One of the main challenges associated with fast charging and discharging is the degradation of the battery’s electrodes, resulting in decreased battery capacity and increased internal resistance. Rapid charge/discharge rates can also cause high heat generation, leading to thermal runaway and damage to the battery’s electrolyte and electrodes.
Fast charging, which generally involves high-rate currents and elevated temperatures, which can lead to accelerated battery aging and compromise its performance. Therefore, the use of fast charging may accelerate battery aging and compromise battery performance .
