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.
In order to operate lithium-batteries safely and optimize their life span, they should not be over-charged or deep discharged. What happens when a battery is over-charged? If neither the charger nor the protection circuit stops the charging process, then more and more energy enters the cell.
Combining the results in The electro-thermal behaviors of the over-discharged lithium-ion batteries in combination with different current rates Section, it can be found that when a battery is over-discharged to 0.5 V at a rate of 0.5C, its discharge capacity is obtained at 1222 mAh.
With the popularity of lithium-ion batteries, especially the widespread use of battery packs, the phenomenon of over-discharge may be common.
With the aid of very low current, an attempt must be made to rebuild the basic voltage so that charging can then resume normally from 3 V,” says Heydecke. Users must therefore ensure that suitable chargers are used and to avoid damaging the devices and batteries.
Rupture of the pouch and separator melting are the two key factors for the initiation of TR during overcharge process. Therefore, proper pressure relief design and thermal stable separator should be developed to improve the overcharge performance of lithium-ion batteries.
