Embodiment

[0090] Production of polyelectrolyte-based electrolytes

[0091] Poly(styrenesulfonic acid) (PSSH) polymer electrolyte was prepared by adding 2 g of PSSH powder into 10 mL of deionized water at room temperature and subjected to ultrasonic bath sonication for 30 min to obtain a clear solution.

[0092] Subsequently, the clear solution was heated to 60°C in a Petri dish for 6 hours to obtain a polymer electrolyte membrane (0.6-0.8 mm thick) (see Image 6 ). The poly(styrenesulfonic acid) (PSSH) polyelectrolyte membrane acts as a separator between the two electrodes, preventing electrical shorting, and as an electrolyte, allowing ionic charge transfer.

[0093] Preparation of conventional electrolytes based on phosphoric acid and PVA

[0094] Polyvinyl alcohol (PVA) acidic polymer electrolyte was obtained by heating 5 g of polyvinyl alcohol (PVA) monomer (Alfa Aesar, 98–99%, medium / high molecular weight) in 50 mL of deionized water at 90 °C to obtain a clear gel colloidal solu...

Abstract

An energy charge storage device, particularly from the group consisting of super capacitor, a hybrid electrochemica 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.

Description

field of invention [0001] The present invention relates to the fields of electrochemistry and polymer chemistry, in particular the electrochemistry of energy charge storage devices. Background of the invention [0002] Electrochemical capacitors (ECs), commonly referred to as "supercapacitors," have been recognized as one of the most important power sources in several devices, including backup storage, hybrid powertrains for electric vehicles, military and medical applications, digital communication systems, And because of their interesting features in terms of high power density and long cycle life, they have been extensively studied. [0003] ECs are electrical appliances with highly reversible charge storage and transfer capabilities. ECs have properties that complement secondary batteries and consist, for example, of carbon-based electrodes and electrolytes. [0004] An electrolyte is any substance containing free ions that act as a conducting medium. Because electrol...
