Abstract: A powder mixture (16) for heat dissipation and a process for forming the powder mixture (16) are disclosed. The powder mixture (16) includes C15H24, a carbonate, an oxide, an oxalate, and two or more materials selected from the group consisting of a chloride and one or more transition metal source. A component having the powder mixture (16) and a process for forming the component are also disclosed. The process for forming the component includes arranging a plurality of cells (12) of the component in an arrangement and filling a powder mixture (16) in interstitial gaps between the cells. The disclosed powder mixture (16) is tested to be very efficient, providing passive cooling, and allowing compact construction of the components. Simple processing of the powder mixture (16) enables an easy implementation of the battery modules in various systems.
