There is also a secondary connection of the SEI layer to LIB safety, and it comes into play once the anode is fully passivated. To avoid lithium plating or dendrite formation at the anode during charging over the life of the cell, capacity is often kept about 10% more than that at cathode [18] (N/P ratio of 1.1 where "N" is the negative electrode, or anode during cell …
When the battery provides current, electrons are moving from the anode to the cathode outside the battery. Applying reverse current allows the battery to recharge itself: the electrons are sent back to the anode and, the lithium ions re-intercalate themselves in the cathode. This restores the battery''s capacity. The whole charging/discharging ...

This represents a large current from a relatively small battery of about 800 milliampere (mAh) hours. A current pulse of 2.4 amperes from an 800 mAh battery, for example, correspond to a C-rate of 3C. This is three times the current rating of the battery. Such high current pulses can only be delivered if the internal battery resistance is low.
