Applying thermal barrier between batteries is one of the most effective method to mitigate thermal runaway (TR) of battery. This work investigated TR of a single battery considering the contact resistance between the battery internal cell and external hard shell, and TR mitigation using equivalent thermal barrier between batteries. The results indicate the contact resistance between the internal cell and external shell is around 0.0207 m2Â·KÂ·W-1. For preventing TR propagation, resistance of thermal barrier should be higher than 0.01242 m2Â·KÂ·W-1.
