Temperature Impact on OCV of Lithium-Ion Cells

When making millivolt- and microvolt-level self-discharge measurements, engineers must take into account the cell’s temperature coefficient of voltage, or TCV, or accuracy may suffer.

MATsolutions' insight:


When measuring the self-discharge levels of Lithium-Ion Cells, it is important to take the TCV, or temperature coefficient of voltage, into consideration. Unless the temperature is absolutely constant, the TCV can have a wide range of impact on the OCV, or open-circuit voltage, so it should always be understood and considered to ensure accuracy.
