WebLithium-ion batteries (LIBs) are employed when high energy and power density are required. However, under electrical, mechanical, or thermal abuse conditions a thermal runaway can occur resulting in an uncontrollable increase in pressure and temperature that can lead to fire and/or explosion, and projection of fragments. In this work, the behavior of LIBs … Webreduction with graphite of the decomposed product into uranium dioxide was observed above 750°C. It was also demonstrated that uranium dioxide and carbide-dispersed graphite-hase fuel could be prepared by thermal decomposition of hexahydrate in the graphite matrix. I.
