Abstract
A moldable mass contains graphite and a phase change material (PCM). The moldable mass further contains a binder and microcapsules having the PCM. A process produces a molding from the moldable mass, and the molding is used to produce various products such as cooling elements, battery temperature control elements, cooling elements for vehicle cabins, electronic components, and motors.
Claims17
A battery configuration, comprising:
- a battery cell pack;
- and
- a cooling element for maintaining a constant temperature of said battery cell pack, said cooling element having a form-fitting connection with said battery cell pack, said cooling element containing:
- graphite;
- a binder selected from the group consisting of epoxy resins and fluoropolymers;
