A short review of the effect of external pressure on the batteries. Monatsh Chem 155, 221–226 (2024)
Customer ServiceAn Analysis of the Experimental Results Applying external pressure can compress the electrode structure of the lithium metal battery and bring the electrode particles into closer contact with each other, and the interface impedance between the electrode and the electrolyte is thus reduced.
The pressure increase improves the cycle life of lithium metal, reduces lithium’s migration curvature in the diaphragm, and avoids direct contact between the positive and anode electrodes that can cause internal short circuit in the battery. 2. Experiments 2.1. Experiment Subjects and Experiment Platforms
Imposing a higher pretension force normally causes the surface pressure of lithium metal batteries to increase. This is because the pretension force enables the components inside the battery to come into closer contact, increasing the contact pressure between the surfaces.
Therefore, as the battery’s cyclical charging and discharging cause the electrolyte diffusion coefficient to drop gradually, greater external pressure is needed to have a significant inhibitory effect on the growth of lithium dendrite. 5. Conclusions
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, , , , , ].
This is mainly due to the continuous extrusion of the battery by the external pressure, which further increases the internal stress, reduces the deposition rate of the lithium metal, affects the reaction driving force of the contact surface between the electrode and the electrolyte, and suppresses the further growth of the dendrite tip.
