Abstract
An energy charge storage device, particularly from the group consisting of super capacitor, a hybrid electrochemical capacitor, a metal hydride battery and a fuel cell, comprising a first and second electrode and an electrolyte wherein the electrolyte comprises a printable polyelectrolyte e.g. polystyrene sulfonic acid (PSSH). The present invention also refers to methods of obtaining such energy storage device.
Claims17
An energy charge storage device comprising a first and second electrode and a printable polymer gel electrolyte positioned between the first and second electrodes, wherein:
- the polymer gel electrolyte forms a separator between the first and second electrodes and is in direct contact with the first and second electrodes,
- said polymer gel electrolyte consists of a printable homopolymeric polyelectrolyte or a printable copolymeric polyelectrolyte,
- said homopolymeric polyelectrolyte comprises a single homopolymer or said copolymeric polyelectrolyte comprises a single copolymer, and
- said energy charge storage device is selected from the group consisting of a supercapacitor, a hybrid electrochemical capacitor, and a metal-hydride battery.
