Many familiar with lithium-ion battery technology will say that it breathes as a byproduct of routine charge/discharge cycles.
However, few methods exist to quantify the internal stress this activity may have on battery life and performance.
If Li-Ion Battery Stack Pressures are Too High? | If Li-Ion Battery Stack Pressures are Too Low? |
Higher rates of capacity fade Plastic deformation/delamination from internal pressure In extreme cases, thermal runaway | Too much movement for thermal expansion in the housing. Plastic delamination/deformation |
Summarized from: Cannarella, J., Arnold, C., “Stress Evolution and Capacity Fade in Constrained Lithium-Ion Pouch Cells”Journal of Power Sources. 245 (2014) 745-75 https://doi.org/10.1016/j.jpowsour.2013.06.165 |
Now, here's where the I-Scan™ pressure mapping system fits in.
 | Thin, conformable sensors offer the ability to capture pressure exchanges across an entire battery cell, orbetween cells. |
 | Identify regions of excessive pressure, which can result in battery failure. |
 | Collect charge/discharge cycle data over multiple months without replacing sensors. |
Pressure measurement provides critical insights to all phases of battery design, research, testing, and manufacturing.
