6 FAQs about [Research background of lithium battery charging and discharging]
Why does a lithium battery have a long charge/discharge cycle?
It may be attributed to the large amount of electroplated lithium produced at the charging rate of 2C. This is confirmed in the subsequent Post-mortem analysis of cells. In addition, during the charge/discharge cycle of cells, it is noticed that the time for each constant voltage charge has prolonged with the cycle.
Do lithium-ion batteries have a capacity loss mechanism?
The charging and discharging processes of the battery are optimized. The capacity degradation is unfavorable to the electrochemical performance and cycle life of lithium-ion batteries, but the systematic and comprehensive analysis of capacity loss mechanism, and the related improvement measures are still lacking.
How does discharge rate affect lithium ion deintercalation?
With the increase of discharge rate, the deintercalation amount of lithium-ion per unit of time increases. A larger concentration gradient will be formed inside the particles to balance the increase of ion deintercalation rate, resulting in an increased internal stress and aggravating the fracture of the particles.
Does charge/discharge rate affect battery capacity degradation?
Based on the electrochemical-thermal-mechanical coupling battery aging model, the influences of the charge/discharge rate and the cut-off voltage on the battery capacity degradation are studied in this paper, and the optimization of the charge/discharge strategy is carried out.
Does undercharging affect charge and discharge characteristics of a Li-ion battery?
In this study the analysis of charge and discharge characteristics of a commercial Li-ion battery is performed under C-rate 0.136 to 0.9 C in order to study the effects of undercharging on voltage profile, charging and discharging time, stored charge (charge capacity) and extracted charge (discharge capacity).
Why does lithium plating occur during charging?
During charging, the lithiation of graphite is weakened, and lithium plating is formed on the anode. It is reported by literature that lithium plating is attributed to the potential drops below 0 V vs. during charging when the resistance of negative electrode reaches a certain amount .
