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.
In order to improve the energy storage and storage capacity of lithium batteries, Divakaran, A.M. proposed a new type of lithium battery material and designed a new type of lithium battery structure, which can effectively avoid the influence of temperature on battery parameters and improve the energy utilization rate of the battery .
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 ].
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.
The start of formation can be defined as the point at which the cell is electrically connected, and the first charge is initiated. Fig. 1 Schematic overview of the formation process and manuscript. The formation begins with a freshly assembled cell (top left battery). The formation of state-of.art LIBs starts with its first connection of the cell.
Based on the experimental results, a battery volume expansion model incorporated with lithium plating and stripping side reactions on the anode is established to simulate the lithium plating induced volume expansion behaviors. The model can successfully reproduce the expansion overshoot during the charging process for the first time.
