6 FAQs about [Large current discharge will cause lithium batteries]
What happens when a lithium ion battery discharges?
When the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve.
What is a constant current discharge of a lithium ion battery?
Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
What is the discharge capacity of a lithium ion battery?
Combining the results in The electro-thermal behaviors of the over-discharged lithium-ion batteries in combination with different current rates Section, it can be found that when a battery is over-discharged to 0.5 V at a rate of 0.5C, its discharge capacity is obtained at 1222 mAh.
Why does the internal resistance of a battery increase with discharge current?
The internal resistance of the battery increases with the increase of the discharge current of the battery, which is mainly because the large discharge current increases the polarization trend of the battery, and the larger the discharge current, the more obvious the polarization trend, as shown in Figure 2.
Are lithium-ion batteries over-discharged?
With the popularity of lithium-ion batteries, especially the widespread use of battery packs, the phenomenon of over-discharge may be common.
Why do lithium batteries fail during high discharge rate?
Overall, it is identified that the main failure factor in LIBs during high discharge rate is attributed to loss of active material (LAM), while loss of active Li-ions (LLI) serves as a minor factor closely associated with formation of devitalized lithium compounds within active materials. 2.
