Key voltage parameters within this chart include rated voltage, open circuit voltage, working voltage, and termination voltage. Nominal value representing the theoretical design voltage of the battery.
The ideal voltage for a lithium-ion battery depends on its state of charge and specific chemistry. For a typical lithium-ion cell, the ideal voltage when fully charged is about 4.2V. During use, the ideal operating voltage is usually between 3.6V and 3.7V. What voltage is 50% for a lithium battery?
The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases. This voltage can tell us a lot about the battery’s state of charge (SoC) – how much energy is left in the battery. Here’s a simplified SoC chart for a typical lithium-ion battery:
Cut-off Voltage: This is the minimum voltage allowed during discharge, usually around 2.5V to 3.0V per cell. Going below this can damage the battery. Charging Voltage: This is the voltage applied to charge the battery, typically 4.2V per cell for most lithium-ion batteries.
A typical lithium ion battery voltage profile is a relationship between voltage and state of charge. When the battery is discharged and current is supplied, the anode releases lithium ions to the cathode to create a flow of electrons from one side to the other. The charge and discharge curves of lithium-ion batteries vary by type.
The voltage of lithium batteries typically ranges from 3.2 to 3.7 volts per cell, depending on the chemistry. The capacity, measured in milliampere-hours (mAh) or ampere-hours (Ah), can vary significantly, usually ranging from 500 mAh to over 5000 mAh. The capacity impacts the battery’s run time and suitability for different devices.
