Abstract
Disclosed in this specification is a method for providing a stretchable power source and corresponding device. The device has at least two stretchable fabrics with silver-coated fibers. Each fabric has cathodic and anodic materials, respectively, deposited between the fibers. The fibers are sealed with an elastomeric pouch having an electrolyte. The stretchable power source has substantially no change in discharge capacity when stretched from 0% strain to 100% strain.
Claims15
A stretchable power source comprising:
- a first stretchable fabric comprising silver-coated first polymeric fibers and a cathodic material deposited between the first polymeric fibers;
- a second stretchable fabric comprising silver-coated second polymeric fibers and an anodic material deposited between the second polymeric fibers;
- an ectrolyte;
- an elastomeric pouch containing the electrolyte, the first stretchable fabric and the second stretchable fabric;
- wherein the stretchable power source has substantially no change in discharge capacity as the stretchable power source is stretched from 0% strain to 100% strain.
A stretchable power source comprising:
- a first stretchable fabric comprising silver-coated first polymeric fibers and Zn deposited between the first polymeric fibers;
- a second stretchable fabric comprising silver-coated second polymeric fibers and MnO2 deposited between the second polymeric fibers;
- an electrolyte;
- an elastomeric pouch containing the electrolyte, the first stretchable fabric and the second stretchable fabric.
A method for forming a stretchable power source, the method comprising:
- soaking a first stretchable fabric comprising silver-coated first polymeric fibers in a first suspension comprising Zn particles and a first liquid;
- permitting a portion of the Zn particles to become embedded in the first polymeric fibers;
- removing the Zn particles that were not embedded in the first polymeric fibers;
- drying to remove the first liquid;
- soaking a second stretchable fabric comprising silver-coated second polymeric fibers in a second suspension comprising MnO2 particles and a second liquid;
- permitting a portion of the MnO2 particles to become embedded in the second polymeric fibers;
- removing the MnO2 particles that were not embedded in the second polymeric fibers;
- drying to remove the second liquid;
- sealing the first stretchable fabric, the second stretchable fabric and an electrolyte within an elastomeric pouch to provide a stretchable power source.
