Depending on the design and chemistry of your lithium cell, you may see them sold under different nominal "voltages". For example, almost all lithium polymer batteries are 3.7V or 4.2V batteries. What this means is that
As detailed above, the battery voltage is the sum of the EMF, given by Nernst's law, and the overvoltages of the two electrodes. In Nernst's law, the potential depends on the species concentration as well as on the temperature.
Angel Kirchev, in Electrochemical Energy Storage for Renewable Sources and Grid Balancing, 2015 The single cell voltage (denoted as Ucell) is the electric potential difference between the positive and the negative battery terminals.
Nominal Voltage: This is the battery's “advertised” voltage. For a single lithium-ion cell, it's typically 3.6V or 3.7V. Open Circuit Voltage: This is the voltage when the battery isn't connected to anything. It's usually around 3.6V to 3.7V for a fully charged cell. Working Voltage: This is the actual voltage when the battery is in use.
For lithium-ion batteries, the nominal voltage is approximately 3.7-volt per cell which is the average voltage during the discharge cycle. The average nominal voltage also means a balance between energy capacity and performance. Additionally, the voltage of lithium-ion battery systems may differ slightly due to variations in the specific chemistry.
By convention, the cell voltage of lead–acid batteries is 2 V; therefore, the nominal battery voltage is always a multiple of 2 V. The voltage of the vehicle system, however, is set somewhat higher than the nominal voltage to operate the battery, given the overvoltage required to recharge lead–acid batteries.
The voltage calculated from equilibrium conditions is typically known as the nominal battery voltage. In practice, the nominal battery voltage cannot be readily measured, but for practical battery systems (in which the overvoltages and non-ideal effects are low) the open circuit voltage is a good approximation to the nominal battery voltage.
