Technology to Improve Lithium-Ion Battery Life and Performance
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 |
|

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, or
|
 |
 |
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.
