Lithium-ion batteries cell thickness changes as they degrade. These changes in thickness consist of a reversible intercalation-induced expansion and an irreversible expansion. In this work, we study the cell expansion evolution under variety of conditions such as temperature, charging rate, depth of discharge, and pressure.
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.
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.

Lithium-ion batteries usually undergo obvious lithiation expansion during charging, because the lithiation-induced volume expansion of the anode materials (graphite and Si/C) is usually larger than the delithiation-induced volume contraction of the cathode materials (LiFePO 4 and LiNi x Co y Mn 1-x-y O 2) [ 17 ].
The expansion overshoot phenomenon, where the battery volume increases beyond the nominal maximum during the constant current charging stage and then decreases during the constant voltage charging or rest stage, can be observed in the lithium-ion batteries charged at high rates or low temperatures [ , , , ].
