6 FAQs about [Lithium polymer battery discharge curve]

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.).

How to determine the discharge capacity of lithium batteries?
