Abstract

The present disclosure provides a pellet composition having enhanced thermal stability for use in a thermally-actuated, current cutoff device. Certain inorganic stability additive particles, such as silica, talc, and siloxane, can be mixed with one or more organic compounds to form a thermal pellet composition. A solid thermal 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 50° C. greater than the T. In certain variations, maximum dielectric capability temperature (T) is greater than or equal to about 380° C.
