Customer ServiceThe 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.
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.
For lithium-ion cells, the SEI layer has been shown to grow over the life of the cell, increasing impedance and decreasing usable capacity . Stack pressure is shown to reduce capacity fade through suppressing delamination of electrodes, gassing of the electrolyte, and SEI layer growth , .
A constant pressure fixture was designed, built, and tested for lithium-ion cells. 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%.
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 .
Lithium-ion pouch cells may not benefit from the capacity increase from stack pressure as with lithium-metal anode and silicon-blend anode cells, where much higher stack pressures showed improvements in capacity , .
