Background/unmet need

Flexible solid-state super-capacitors attract more and more attention as the power supply for wearable electronics. To fabricate such devices, the flexible and economical current collectors are needed. Potential materials for use in these super-capacitors include stainless steel, Li-ion batteries, and polymer films treated with conductive coatings However, a material with the desired properties of capacitance, mechanical strength, flexibility, and durability has not yet been discovered. The achievement of such a high-performance and flexible super-capacitor can open up exciting opportunities for wearable electronics and energy storage applications.

Invention Description

Researchers at the University of Texas at Austin have developed a method to produce a super-capacitor with a cord-yarn structure. This technology includes the use of activated carbon fiber (ACF) and carbon fiber (CF) for ply yarn formation, electrolyte gel preparation, and super-capacitor assembly.


  •  First indication that a flexible line supercapacitor can be produced
  • Production occurs using a traditional textile process for cord-yarn formation


  • Extreme flexibility
  • High capacitance
