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.
If you want to avoid your lithium-ion batteries self-discharging when fully charged, then you should avoid fully charging them. If you charge your batteries up to only 90-95% of their capacity, then they won’t self-discharge as much.
The most common cause of lithium battery self discharge is moisture. The electrolyte solvent or water in the battery get dissolved by the moisture, creating an imbalance in the electrolyte of the battery. When this happens, an electric short will be created and a lithium ion leak will occur, causing a fire.
When a lithium-ion battery is not in use, it will lose some of its charge. This is known as self-discharge and it’s a natural process that occurs with all batteries. Study shows that batteries happens to discharge even faster when the battery isn’t being used properly or stored in suboptimal conditions.
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.
The activity of the electrolyte is enhanced, and the side reactions between the electrolyte and the electrode are intensified. Temperature do impacts the self-discharge of lithium battery or lithium cell. You can expect the self-discharge to typically double for every 10°¢ rise. 3. Electrolytic Solvents
