Carrar says its immersion-cooled battery architecture stops thermal runaway even with a cell above 800 °C

Carrar says testing at its R&D lab showed its Two-Phase Immersion Architecture can prevent thermal propagation between high-energy NMC pouch cells even under extreme failure conditions. In the test, a 72 Ah pouch cell was driven into thermal failure with a temperature rise exceeding 15 °C per second, and the triggered cell rose above 800 °C, while an adjacent cell remained at about 50 °C, according to the company. The company says the result dem…
