It is safely impossible to drop an ideal battery to zero volts. A battery cannot go down to zero volts because of the internal chemistry. In a standard use, you cannot drop the voltage below 2 volts, even if you wired the terminals together. Batteries will vary between 3.8 and 2.4 volts per cell. As voltage drops, internal resistance rises.

The current rate has an upper limit during such process. It generally appears in some extreme cases, for example, when the battery pack suffers impact or when it is socked in water. The battery voltage will suddenly drop close to zero and maybe jump back and forth when an external short circuit happens [30]. When the SOC of a …
$begingroup$ You''re probably confusing what "last longer" means. You will only get 80% of energy per charge cycle, but that cycle will "damage" your battery 5x less than charging it to 100%.So in far future, you get 5x 80% = 400%, instead of 1x 100% = 100% of the power. In other words, you will be able to charge the battery many more …

A battery is made up of an anode, cathode, separator, electrolyte, and two current collectors (positive and negative). The anode and cathode store the lithium. The electrolyte carries positively charged lithium ions from the anode to the cathode and vice versa through the separator.
Because lithium-ion batteries incorporate a BMS which protects the cells from unsafe voltage, current and temperature, the battery will not enter these conditions. Due to these hard stops in the BMS, performance will suffer and overall effective pack capacity will be reduced corresponding to the level of imbalance if nothing is done.

lithium formation should be avoided because it will shorten the life of the battery. Metallic lithium will react will the electrolyte and become deactivated. The result is permanent capacity loss. As a benchmark, typically, 20 percent of the cell capacity is lost at 300 cycles, from all causes using 0.8C/4.20V CC/CV charging for 2.5 hours.
