Capacitors exhibit remarkable power density while batteries have excellent energy density. Supercapacitors offer a good combination of energy and power density. I demonstrated two different supercapacitor designs from niobium nanowires. The first design is in the form of a yarn, suitable for wearable, flexible, and stretchable devices (Figure A) and the second design is a planar supercapacitor suitable for micro-electronics (Figure B).
