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 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.

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. Experimental section 2.1. Battery samples

What is a discharge curve in a lithium ion battery?

The discharge curve basically reflects the state of the electrode, which is the superposition of the state changes of the positive and negative electrodes. The voltage curve of lithium-ion batteries throughout the discharge process can be divided into three stages

What does deep discharge mean on a lithium ion battery?

The depth of discharge refers to the percentage of a battery’s total capacity utilized during a discharging cycle. While lithium-ion batteries can handle shallow discharges without much impact on their longevity, deep discharges, especially below 20% DoD, can cause strain on the battery and reduce its lifespan.

How does temperature affect lithium ion discharge?

Essentially the charge is a process of some "order" in lithium ions deposition. So a higher temperature works against this process and slows the ordering down. The discharge process is sort-off "disordering", and goes more intensively with increase of temperature. The Joule heat, however, warms up the Li-Ion cell in both cases.
