6 FAQs about [Lithium battery expansion calculation]

Are expansion measurements necessary for battery state estimation and definition?

To evaluate the necessity of expansion measurements for battery state estimation and definition, the University of Michigan Battery Laboratory (UMBL) dataset is utilized. Then, the relationships between expansion characteristics and SOH/SOC are deeply analyzed.

How is the expansion of a battery measured?

The expansion was measured using a displacement sensor (Keyence, Japan) mounted on the top plate. The dynamic testing were carried using a battery cycler (Biologic, France). The temperature was measured using a K-type thermocouple (Omega, USA) placed on the surface of the battery. Table I. The pouch cell specifications.

How do you find the thermal expansion coefficient of a battery?

Since it was assumed that the temperature is uniform in the cell, a lumped expansion model is also considered for the battery. Therefore, the thermal expansion, Δ tth, is given by where αth is the thermal expansion coefficient of the battery.

How does thermal expansion affect lithium ion batteries?

Thermal expansion depends on the current, DOD and the location on cell. Larger thermal stress can lead to capacity fade and safety issue of lithium-ion batteries. Thermal expansion is induced by thermal stress due to the temperature deviation during charge-discharge cycles.

What factors affect the expansion of a battery?

However, for the expansion at the battery level it is also necessary to consider the influence of the inactive components such as the separator, current collectors, and casing. The expansion and the strain rate during battery cycling is small enough to consider a linearized regime for the deformation of these components.

What is the relationship between expansion and battery States?

According to the relationship between expansion and battery states, new definitions of SOH and SOC based on expansion are proposed.
