Abstract:
In einem Verfahren zur Herstellung einer als elektrochemische Speichervorrichtung (26) ausgebildeten Faserverbundstruktur (22) werden elektrisch leitfähige Fasern (20) zu einer Elektrode (23) und einer Gegenelektrode (24) angeordnet und mit einem mit einem Elektrolytmaterial (3) dotierten Harz (4) getränkt. Während eines Aushärtens des Harzes (4) wird eine elektrische Spannung, insbesondere eine Wechselspannung,an die Elektrode (23) und die Gegenelektrode (24) angelegt. Ein Faserverbundbauteil (22), das als elektrochemische Speichervorrichtung (26) ausgebildet ist, weist elektrisch leitfähige Fasern(20), die eine Elektrode(23)und eine Gegenelektrode (24) ausbilden, und eine Harzmatrix (5) auf, die mit einem Elektrolytmaterial (3) dotiert ist. Das Elektrolytmaterial (3) bildet nicht-sphärische, in eine Vorzugsrichtung (7) orientierte Einlagerungen (6) in der Harzmatrix aus.

Abstract:
An energy storage device comprises a capacitor having a dielectric between opposite electrodes and a nonconductive coating between at least one electrode and the dielectric. The nonconductive coating allows for much higher voltages to be employed than in traditional EDLCs, which significantly increases energy stored in the capacitor. Viscosity of the dielectric material may be increased or decreased in a controlled manner, such as in response to an applied external stimulus, to control discharge and storage for extended periods of time.
