Get a quoteWhen you analyze the discharge characteristics of li-ion batteries, you focus on the charge-discharge curves. These curves show how voltage and current change as the battery charges and discharges. You typically see a flat discharge curve in lithium-ion cells, which means the voltage remains stable through most of the discharge cycle.
Avoid Complete Discharge: Avoiding complete discharge significantly benefits lithium-ion batteries. Complete discharge can trigger a protection mechanism that makes it difficult to recharge the battery.
Understanding Over-Discharge in Lithium-Ion Batteries Over-discharging occurs when a lithium-ion battery is discharged beyond its minimum voltage limit. This can happen due to excessive use, improper charging, or a malfunctioning battery management system (BMS).
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.
These curves show how voltage and current change as the battery charges and discharges. You typically see a flat discharge curve in lithium-ion cells, which means the voltage remains stable through most of the discharge cycle. This stability is essential for battery pack reliability in industrial, medical, and robotics applications.
Part 1. What is a lithium-ion battery and why discharge depth matters? Lithium-ion (Li-ion) batteries operate through complex electrochemical processes where lithium ions shuttle between graphite anodes and metal oxide cathodes (typically NMC or LFP chemistry). Their 3.0V-4.2V/cell voltage range is critical because:
