Constant pressure improved discharge power and resistance up to 4% and 2.5%. Current research involving applying stack pressure to lithium-pouch cells has shown both performance and lifetime benefits.
Here, failure mechanisms of lithium metal are investigated in all-solid-state batteries as a function of stack pressure, and in situ characterization of the interfacial and morphological properties of the buried lithium is conducted in solid electrolytes.
The stack level mechanical pressure will be inevitably generated among the battery cells, which dramatically affects the battery properties. To accurately characterize the battery performance with such aspects, an equivalent mechanical model with full consideration of stack pressure is proposed in this paper.
A study conducted by Louli et al. found that 1.7 MPa of stack pressure provided the highest performance for a lithium-metal negative electrode cell using a liquid electrolyte; However, the study reported a 50%–300% change in pressure from the thickness change of the cell during charging and discharging.
However, the pouch batteries are constrained by the shell of the battery pack rigidly under working conditions. So the generation of the stack level mechanical pressure in the battery pack is inevitable due to preloading and volume expansion of batteries [ 17, 18 ]. It is necessary to build a model that fully considers these mechanical factors.
Hahn et al. found that stack pressure decreased lithium-ion cell capacity initially, then provided better capacity retention during calendar ageing. The possible benefits of dendrite growth suppression, gas suppression, and SEI layer growth suppression would only emerge with degradation testing and/or calendar ageing. Fig. 8.
