Abstract
(A1) Die vorliegende Erfindung betrifft eine Redox-Flow-Batterie, welche einen Elektrolyten aufweist, der zumindest eine ionische Fluessigkeit enthaelt.
WO 2010094657 A1 UPAB: 20100908 NOVELTY - The redox-flow-battery comprises a water-free electrolyte having ionic fluid, positive and negative half cells (f) having ionic fluid, where the ionic fluids are same or different, and vanadium ions (V4+/V5+) as redox-pair for the positive half cell and V4+/V3+ as the redox pair for the negative half cell. The electrolyte comprises 0.1 wt.% of the ionic liquid(s). The operating temperature of the redox-flow-battery is -30 degrees C to 400 degrees C. The concentration of the vanadium ion in the electrolyte is 0.1-10 mol/l. DETAILED DESCRIPTION - The redox-flow-battery comprises a water-free electrolyte having ionic fluid, positive and negative half cells (f) having ionic fluid, where the ionic fluids are same or different, and vanadium ions (V4+/V5+) as redox-pair for the positive half cell and V4+/V3+ as the redox pair for the negative half cell. The electrolyte comprises 0.1 wt.% of the ionic liquid(s). The operating temperature of the redox-flow-battery is -30 degrees C to 400 degrees C. The concentration of the vanadium ion in the electrolyte is 0.1-10 mol/l. The redox pair is formed from the ionic liquid in both half cells of the redox-flow-battery. The electrolyte does not include the additive of stabilizing agent, acids and/or bases. The electrode (b) of the battery is metallic electrode, diamond electrode or indium-tin-oxide electrode. USE - Used as redox-flow-battery. ADVANTAGE - The redox-flow-battery has improved variability in selection of operating parameters such as temperature or selection of electrode material.
