Excessive internal gas accumulation during thermal events leads to catastrophic casing failure. Mitigating this risk prevents violent cell rupture and systemic propagation.

Excessive internal pressure within battery enclosures leads to structural rupture or catastrophic explosion. Mitigating this risk prevents thermal runaway propagation and ensures housing integrity during cell malfunction.

Rapid accumulation of gases or thermal expansion within sealed enclosures causes structural rupture or explosion. Managing these pressure differentials prevents catastrophic housing failure and moisture ingress.
