Background/unmet need

Flexible solid-state supercapacitors attract more and more attention as the power supply for wearable electronics. To fabricate such devices, flexible and economical current collectors are needed. Potential materials for use in these supercapacitors 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 supercapacitor can open up exciting opportunities for wearable electronics and energy storage applications.

Invention Description

Researchers at The University of Texas at Austin have developed method to produce a supercapacitor with all-fabric materials. The technology includes use of activated carbon fiber (ACF) fabric, carbon fiber (CF) fabric, and mesh fabric to form a multilayer composite structure, electrolyte gel preparation, and supercapacitor assembly.

Benefits/Advantages

  • Lightweight materials
  • Low cost of production
  • Possibility for immediate commercial production; all materials are carbon-fiber based

Features

  • All-fabric construction
  • Produced using a traditional textile process for fabric formation

Market potential/applications

Enables a self energy supply product for individuals in an extreme environment for survival, such as military operations in deserts or jungles, or a rescue mission in remote areas.
