What happens after a short circuit in a battery?

After an internal short circuit occurs, batteries with thicker electrodes exhibit a larger number of broken particles in the cathode material and a higher degree of surface roughness on the broken particles. After an internal short circuit occurs, the intensity of the internal electrochemical reactions in NCM far exceeds that of LFP.

What happens if Li + is used in a short circuit?

For thick electrodes, a large amount of Li + will preferentially intercalate into the material particles in the upper layer of the cathode during a short circuit, causing the volume of the lithiated region to expand while the non-lithiated region remains unchanged.
