摘要： The present disclosure relates to thermal cutoff device pellet composition. Provided is a pellet composition having enhanced aging performance, electrical performance, pellet output, pellet density and pellet crush strength for use in a thermally-actuated, current cutoff device. The solid thermal pellet composition comprises an organic compound having a low vapor pressure at room temperature, such as tetraphenylsilane. The thermal pellet composition comprising tetraphenylsilane can significantly improve interruption performance, pellet output, pellet density, pellet crush strength and aging performance of the thermal cutoff device.
