Abstract
Provided is a pellet composition having enhanced thermal stability for use in a thermally-actuated, current cutoff device. The solid thermal pellet composition comprises an organic compound have low ionization potential, such as dibenzosuberenone. The solid pellet maintains its structural rigidity up to a transition temperature (T), but further has improved overshoot temperature ranges. Therefore, the improved thermal pellets have a maximum dielectric capability temperature (T), above which the pellet composition may lose substantial dielectric properties and conducts current that is at least 160° C. greater than the T. The aging performance is further enhanced. Further, methods of enhanced processing and pelletizing are provided.
