This is more of a academic question is suspect, but if you know the answers please post.
This would be for all lifepo4 batteries (I assume).
Why is it that the charge rate is always lower then the discharge rate (lets say the Victron superpack - Charge - 15 / Discharge 30 for 12.8V).
I did a few internet searches, but most is referring to settings and/or capabilities of the cells, but it does not state why it is from a physics stand point.
Is it due to the internal resistance or layer formation that reduces the active sites in the electrode? If it is the internal resistance that decreases during charging, is it due to the electrode and electrolyte morphology changes i.e. the passing current? If so, why only to one direction (viz a viz, charge vs discharge) (easier movement of ions)?
