The fixture applies a constant stack pressure to the face of the battery through the pneumatic actuator and is transferred through two carbon-inlaid 3D-printed plates. This material electrically isolates the battery to prevent the risk of short circuits and provides sufficient stiffness to improve pressure distribution.
Improved lithium batteries are in high demand for consumer electronics and electric vehicles. In order to accurately evaluate new materials and components, battery cells need to be fabricated and tested in a controlled environment.
As both Li-ion and Li-metal batteries utilize Li containing active materials and rely on redox chemistry associated with Li ion, we prefer the term of “lithium batteries” (LBs) to refer to both systems in the following context.
The performance impacts of constant pressure on lithium-ion pouch cell is relatively unknown. As previously discussed, constant pressure research has been previously focused on low amplitude (< 40 N Jiang et al. ) or amplitudes above 1 MPa for lithium-metal chemistries .
Two fixtures compared constant pressure and constant displacement effects on cells. The pressure fixture held pressures within −40% to ＋25%. 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.
