The test results demonstrate that high-power charging significantly impacts the durability and thermal safety of the high-capacity lithium batteries. In particular, the capacity fading rate can reach up to 30% only after 100 charge cycles depending on the battery type.
At higher constant charging current rates the battery charges more effectively and this does not only apply to the Vanbo Battery (battery Sample 01) that was tested before but it was also true for the Winbright battery (battery sample 02) tested too.
High charging rates can generate significant heat, potentially causing the battery temperature to rise rapidly, which in turn may affect its performance and lifespan . Batteries have higher charging efficiency at appropriate temperatures, while their charging efficiency decreases at temperatures that are too high or too low.
Further, the migration characteristics of the temperature threshold of battery thermal runaway are investigated using the proposed procedure. The test results demonstrate that high-power charging significantly impacts the durability and thermal safety of the high-capacity lithium batteries.
Connecting a higher-current power supply to a lithium-ion charger will damage the battery. Why? I am not asking how the battery gets damaged, because that answer is straightfoward. What I am asking is why lithium-ion chargers allow batteries to be damaged by excessive charge current in the first place.
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 .
