For example, almost all lithium polymer batteries are 3.7V or 4.2V batteries. What this means is that the maximum voltage of the cell is 4.2v and that the "nominal" (average) voltage is 3.7V. As the battery is used, the voltage will drop lower and lower until the minimum which is around 3.0V.
Famous for their stability, safety, and extended cycle life, LiFePO4 batteries provide a nominal cell voltage of 3.2 volts. This contrasts with conventional lithium-ion batteries, which usually have a nominal value ranging from 3.6 to 3.7 volts per cell.
Li-ion batteries have a voltage and capacity rating. The nominal voltage rating for all lithium cells will be 3.6V, so you need higher voltage specification you have to combine two or more cells in series to attain it.
Voltage limits. Lithium-ion cells are susceptible to stress by voltage ranges outside of safe ones between 2.5 and 3.65/4.1/4.2 or 4.35V (depending on the components of the cell). Exceeding this voltage range results in premature aging and in safety risks due to the reactive components in the cells.

Lithium-ion batteries have a nominal voltage of 3.6V or 3.7V per cell. However, the working voltage of a lithium-ion battery can range from 2.5V to 4.2V per cell, depending on the chemistry and design of the battery.
The nominal voltage of lithium-ion is 3.60V/cell. Some cell manufacturers mark their Li-ion as 3.70V/cell or higher. This offers a marketing advantage because the higher voltage boosts the watt-hours on paper (voltage multiplied by current equals watts).
Here we look back at the milestone discoveries that have shaped the modern lithium-ion batteries for inspirational insights to guide future breakthroughs.
