KULR Technology’s patented Thermal Capacitor is a revolutionary solution designed to absorb and redistribute thermal energy in a system, effectively damping thermal spikes and delaying temperature rise. This customizable solution is available in various form factors and core thermal properties, thanks to its fully adaptable design. Utilizing KULR’s unique oriented carbon fiber technology, the Thermal Capacitor can efficiently and evenly transfer heat into a phase change material (PCM), resulting in a lightweight and sustainable solution that can withstand harsh environments for decades. The Thermal Capacitor has been successfully implemented in high-reliability applications such as the Mercury Messenger, ISS NICER, and the Perseverance Mars Rover.
