Passively Thermal Runaway Propagation Resistant Battery Module that Achieves > 190 Wh/kg
Highly thermally conductive interstitial materials between tightly nested, small Li-ion cells that also provides structural support to the cell can walls are critical for preventing adjacent cells from cascading into thermal runaway. Verification of these high performing designs has only been possible with specially made trigger cells implanted with a NREL/NASA invented internal short circuit device.
