Abstract:
A reduced graphene oxide electrode with a three-dimensional porous structure is synthesized based on a facile electro-reduction strategy with subsequent freeze-drying. The 3D architecture enables the full penetration of the PVA-NaClO4 hydrogel electrolyte, giving rise to a 1.6 V quasi-solid-state symmetric supercapacitor with good flexibility, good temperature/pressure tolerance and high areal/volumetric energy and power densities.

Electrolytes: van't Hoff Factor
The colligative properties of a solution depend only on the number, not on the identity, of solute species dissolved. The concentration terms in the equations for various colligative properties (freezing point depression, boiling point elevation, osmotic pressure) pertain to all solute species present in the solution. Nonelectrolytes dissolve physically without dissociation or any other accompanying process. Each molecule that dissolves yields one...
