6 FAQs about [Battery pack capacity expansion]

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 thermal expansion coefficient of a battery?

where αth is the thermal expansion coefficient of the battery. The total expansion of the electrodes in the cell is simply the sum of the expansion of individual electrodes. Furthermore, in the case of this paper, the battery consists of multiple layers of cells stacked on top of each other in a pouch cell.

What causes volume expansion of lithium ion batteries?

Volume expansion of lithium-ion batteries is caused by lithium (de-)intercalation, thermal expansion, and side reactions (such as lithium plating and gas generation) inside the battery. In this work, the battery is kept in a constant ambient temperature.

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.

What is the thermal expansion coefficient of a pouch battery?

According to literature [ 19, 24, 25 ], the overall thermal expansion coefficient of similar-sized pouch batteries is about 1.1–1.2 μm/°C. And the calculated maximum thermal expansion is about 0.72 μm, which is less than the measurement accuracy of the displacement sensors.
