6 FAQs about [Battery pulse discharge failure]

How does a short discharge pulse affect a battery?

What happens if a battery fails to supply a pulsed current?

At the end of life the battery will easily support a small continuous current, but may fail to supply the pulsed current at a voltage necessary for the application. 4. Different cells from the same batch may act differently, so don't depend on testing a single cell.

What happens if a battery is discharged too much?

As we mentioned above, excessive discharge current can cause the battery to generate a large amount of heat, leading to oxidative decomposition of the electrolyte and reconstruction of the SEI, leading to delamination of the active material layer and causing a damage on the crystalline structure of NCM cathode.

What causes a battery to lose capacity when discharged quickly?

The answer depends on what is causing the battery to lose capacity when discharged quickly. Resistance losses internal to the battery will increase as a proportion of the load resistance as the current goes up.

How does pulse charging affect battery performance?

Firstly, using the C–R pulse mode, it was determined that pulse charging has a positive impact on shortening the charging time for both LFP batteries and NMC batteries, and a smaller frequency is the key to improving battery performance and shortening the total charging time. For the C–R mode, the pulse current amplitude has the greatest impact.

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.
