The most important key parameter you should know in lithium-ion batteries is the nominal voltage. The standard operating voltage of the lithium-ion battery system is called the nominal voltage. For lithium-ion batteries, the nominal voltage is approximately 3.7-volt per cell which is the average voltage during the discharge cycle.
The voltage of the lithium ion battery drops gradually as it discharges, with a steep drop in voltage only towards the end. This rapid drop in voltage towards the end of the discharge cycle is the reason why Li-ion batteries need to be managed carefully to avoid deep discharges that can reduce their cycle life.
Lithium-ion batteries function within a certain range at which their voltage operates optimally and safely. The highest range where the fully charged voltage of a lithium-ion battery is approximately 4.2V per cell. The lowest range which is the minimum safe voltage for lithium-ion batteries is approximately 3.0V per cell.
Typically, high voltage batteries tend to have longer lifespans and cycle lives compared to low voltage batteries due to superior materials used in their construction. What Innovations Are Emerging in HV and LV Battery Technologies?
For devices requiring compact designs and high energy densities, lithium-ion batteries with a higher nominal voltage of lithium-ion are used. For applications requiring low energy densities and higher safety along with long cycles, LiFePO4 cells with a slightly lower nominal voltage are thus used frequently.
Additionally, the voltage of lithium-ion battery systems may differ slightly due to variations in the specific chemistry. For example, the nominal voltage of LiFePO4 batteries (a lithium-based popular alternative) is 3.2V per cell which is significantly lower than Litium-ion batteries’ average voltage (3.7V).
