Carbon fiber-based electric vehicle body panel stores energy and achieves an unprecedented 100,000 charge-discharge cycles


This technology is a hierarchical architecture‐based carbon fiber for storing energy. The CASE electrode invention has an unprecedented 100,000 charge‐discharge cycles with less performance degradation. Currently, the electric vehicle industry is targeting to achieve more than 500 miles/charge. To increase the miles/charge of the electric vehicles, more energy storage devices should be added but will further increase the net weight of the cars resulting in more energy required for vehicle propulsion. A practical direction to increase the miles/charge without adding the extra weight is to store energy in the body panels of the vehicles. This can be achieved by using carbon fiber‐based composite supercapacitors which can act as both energy and structural component of the car body. The UCF CASE composite supercapacitor offers reduced net weight, extra miles/charge, longer cycle life, and more protection than the existing aluminum or steel body used for electric vehicle panels which acts as only the structural component.

Key Benefits

• Achieves 100,000 charge-discharge cycles with less performance degradation
• Light-weight CASE fibers can be converted into carbon fiber composites with high tensile strength
• Reduces the net weight of the vehicle and at the same time increases the miles/charge of the vehicle
