However, high-power charging may negatively affect the durability and safety of lithium batteries because of increased heat generation, capacity fading, and lithium plating, which can induce the risk of battery thermal runaway.
The energy density of the currently available lithium batteries should be significantly increased to support the operation of such vehicles, and high-power charging is required to reduce the charging time.
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.
After 100 charging cycles of 1 C charge and 1 C discharge, the capacity fluctuates between 21.8 Ah and 22.3 Ah, which is acceptable. When charging at 3 C, the maximum capacity of the battery drops from 19.1 Ah to 17.4 Ah. As the cycles progressed, the maximum chargeable capacity of the battery decreases significantly.
On the other hand, high-rate charging and discharging can also negatively impact the heat generation and safety performance of lithium-ion cells ( Ouyang et al., 2019, Zhang et al., 2022b, Li et al., 2019, Fleischhammer et al., 2015, Huang et al., 2019, Ziat et al., 2021 ).
