Variation in the big frequency resistance of the lithium-ion battery with external force might be brought about through discrepancy in the contact resistance amongst various ingredients of the lithium-ion battery. In addition, it can be caused by compression of the electrodes and separator deformation .
Figure 15 characterizes lithium-ion battery impedance with and without external force for a new lithium-ion battery in a Nyquist plot. An overall growth of impedance accompanied by the external force could be seen. The big frequency resistance, which is the intercept with the real axis, was considerably influenced by the external force.
The effect of externally and internally mechanical stresses on lithium-ion batteries’ electrochemical performance was studied . Focused attention was paid to the dependency of the ion transport inside the separator against the stress condition. It was concluded that external pressure on the battery cell brings about stresses .
In addition, determination of the effect of external force on the performance and behavior of a prismatic lithium-ion battery cell was investigated. Initially, the primary aim was to present the impedance properties variation in external static force conditions for the prismatic lithium-ion battery cell.
An alteration of impedance was recognized simultaneously as external compressive load was applied to the lithium-ion battery. There was a negligible variation of Ohmic resistance while external compressive load was applied at different state of charge. The corresponding minor variation did not depend on state of charge level.
On the contrary, several authors have reported , , , , , , that an appropriate external pressure can benefit the lifespan and safety of both liquid- and solid-electrolyte based cells by improving the contact conditions and suppressing the growth of lithium dendrites [17, , , , , ].
