It depends on the battery. You can discharge some batteries until 0-10 % and battery life won''t be reduced. Examples: NCA (Nickel-cobalt-aluminum) and LTA (Lithium titanate oxide) lithium-ion batteries. The final state of charge (SOC) is 0-10 % and the depth of discharge (DOD) is 100-90 %.
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.
When the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve.
Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
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.
Full eruptions should be avoided because they put additional strain on the battery. Studies have shown that a lithium-ion battery regularly discharged to 50% before recharging will have a longer lifespan and may retain up to 1,500-2,500 cycles, compared to just 500-1,000 processes if regularly fully discharged.
The demand for high safety and high reliability lithium-ion batteries (LIBs) is strongly considered for practical applications. However, due to their inherent self-discharge properties or abuse, LIBs face the threat of over-discharge, which induces premature end of life and increased risk of thermal runaway.

Once a lithium-ion battery is fully charged, keeping it connected to a charger can lead to the plating of metallic lithium, which can compromise the battery''s safety and lifespan. Modern devices are designed to prevent this by stopping the charge when the battery reaches 100%.
Therefore, when lithium-ion batteries discharge at a high current, it is too late to supplement Li + from the electrolyte, and the polarization phenomenon will occur. Improving the conductivity of the electrolyte is the key factor to improve the high-current discharge capacity of lithium-ion batteries.

1. Understanding the Discharge Curve. The discharge curve of a lithium-ion battery is a critical tool for visualizing its performance over time.

For example, lithium-ion batteries have a high energy density and can discharge quickly, making them ideal for use in portable electronic devices. Nickel-cadmium batteries, on the other hand, have a lower energy density but can be discharged and recharged many times, making them ideal for use in power tools and other high-drain devices.
