What is a lithium battery discharge curve?
The lithium battery discharge curve is a curve in which the capacity of a lithium battery changes with the change of the discharge current at different discharge rates. Specifically, its discharge curve shows a gradually declining characteristic when a lithium battery is operated at a lower discharge rate (such as C/2, C/3, C/5, C/10, etc.).
What is a flat discharge curve in a lithium ion cell?
This discharge curve of a Lithium-ion cell plots voltage vs discharged capacity. A flat discharge curve is better because it means the voltage is constant throughout the course of battery discharge.
What is a lithium battery charging curve?
The lithium battery charging curve illustrates how the battery's voltage and current change during the charging process. Typically, it consists of several distinct phases: Constant Current (CC) Phase: In this initial phase, the charger applies a constant current to the battery until it reaches a predetermined voltage threshold.
