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 , .
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%.
How Pressure Mapping Insights Improve Battery Performance and Safety - Charging and discharging causes changes in temperature, electrochemistry, or volume expansion. Measuring changes in pressure can tell you how the mechanics of the internal components are affected.
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 , .
Lithium-ion batteries (LIBs) have found wide applications in a variety of fields such as electrified transportation, stationary storage and portable electronics devices. A battery management system (BMS) is critical to ensure the reliability, efficiency and longevity of LIBs.
