The Skoltech suggests otherwise. Scientists rejected the plans that the use of ions and electrolytes, and return to the classic "two electrodes and insulator between them." The space between the electrodes is filled nanotubes boron nitride. It's a unique material strength and elasticity, a good insulator. Layer thickness of only ...

This configuration enables us to extend the supercapacitor, overcoming the limitation that conventional configurations of supercapacitor, the two electrodes start to move in comparison with the separation under tension.
