The electrical potential difference between the two electrodes of an electrochemical cell.
This varies by chemistry with common examples below:
- Alkaline manganese primary = 1.5V
- Zinc Carbon Primary = 1.5V
- Lithium manganese dioxide primary = 3.0V
- Lithium thionyl chloride primary = 3.6V
- Nickel cadmium rechargeable battery = 1.2V
- Nickel metal-hydride rechargeable = 1.2V
- Nickel Zinc rechargeable = 1.6V
- Lithium-ion rechargeable = 3.7V
- Lithium-polymer rechargeable = 3.7V
- Silver Oxide Primary = 1.55V
- Zinc Air Primary = 1.45V
Note: Values are for the nominal voltage which is at 50% SoC and at room temperature.
