Yes, it is dangerous to attempt to charge a deeply discharged Lithium battery. Most Lithium charger ICs measure each cell's voltage when charging begins and if the voltage is below a minimum of 2.5V to 3.0V it attempts a charge at a very low current . If the voltage does not rise then the charger IC stops charging and alerts an alarm.
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.
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. Experimental section 2.1. Battery samples
No, it is not OK to have a Li-Ion deeply discharged at all. Here is why: When discharged below its safe low voltage (exact number different between manufacturers) some of the copper in the anode copper current collector (a part of the battery) can dissolve into the electrolyte.
During fast discharging, the Li + ions rapidly intercalate into the cathode and deintercalate from the anode, resulting in a significant lithium concentration gradient, strain mismatch between different parts of the electrode particle, and stress development.
In such scenarios, excessive removal of lithium ions results in mechanical strain, causing delamination of the active material layer and structural damage to the cathode material. As a result, there is consistently observed capacity degradation, particularly under high discharging rates.
