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.
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.
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 ].
During charging process, lithium-ion batteries undergo significant lithiation-induced volume expansion, which leads to large stress in battery modules or packs and in turn affects the battery's cycle life and even safety performance [ , , , ].
