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.).
The voltage of the lithium ion battery drops gradually as it discharges, with a steep drop in voltage only towards the end. This rapid drop in voltage towards the end of the discharge cycle is the reason why Li-ion batteries need to be managed carefully to avoid deep discharges that can reduce their cycle life.
The discharge characteristics of lithium-ion batteries are influenced by multiple factors, including chemistry, temperature, discharge rate, and internal resistance. Monitoring these characteristics is vital for efficient battery management and maximizing lifespan.
