Invention Reference Number
Oak Ridge National Laboratory (ORNL) has developed advanced hybrid ceramic dielectric composites that enhance capacitor performance for demanding power electronics applications. by combining desirable attributes from multiple material classes, this innovation enables capacitors to operate reliably at high temperatures with reduced size and improved efficiency. This advancement addresses the need for compact, durable, and cost-effective energy storage components critical to electrified transportation and other high-performance systems.
Description
The shift toward electrified transportation and advanced energy systems requires power electronic components that are smaller, lighter, and more reliable under extreme operating conditions. Capacitors, as a key element of these systems, present a major bottleneck due to their size and thermal limitations. ORNL researchers have created a new class of dielectric composites that integrate beneficial characteristics of ceramic and polymer materials into a hybrid structure. This approach allows the resulting materials to achieve improved dielectric properties while maintaining structural integrity and stability under elevated temperatures. The composites demonstrate high dielectric constants under standard operating conditions and maintain performance even in harsh thermal environments. By overcoming limitations associated with current dielectric materials, these hybrid composites provide a pathway toward capacitors that are more compact, efficient, and better suited for next-generation power electronics, particularly in electric vehicle and high-temperature industrial applications.
