電気エネルギーを貯蔵するためのレドックスフロー電池及びそれの使用
Document Type and Number:
Japanese Patent JP6814366
Kind Code:
B2
Abstract:
Disclosed is a cost-effective and long-living redox flow cell using less corrosive redox-active components.The redox flow cell comprises a reaction cell having two electrode chambers for catholyte and anolyte, which are each connected to at least one store for liquid and are separated by an ion-conducting membrane, and which are equipped with electrodes, wherein the electrode chambers are each filled with electrolyte solutions comprising redox-active components dissolved or dispersed in an electrolyte solvent, as well as optionally conducting salts dissolved therein and optionally further additives. The redox flow cell is characterized by the anolyte comprising a redox-active component having one to six residues of formula I in the molecule or having one to six residues of formula II in the molecule and by the catholyte comprising a redox-active component having one to six residues of formula III in the molecule or having iron salts or by the anolyte and the catholyte having a redox-active component comprising one to six residues of formula I or of formula II in combination with one to six residues of formula III in the moleculewhereinR1 is a covalent C—C-bond or a divalent bridge group,R2 and R3 independently of one another represent alkyl, alkoxy, haloalkyl, cycloalkyl, aryl, aralkyl, heterocyclyl, halogen, hydroxy, amino, nitro or cyano,X is a q-valent inorganic or organic anion,b and c independently of one another are integers from 0 to 4,q is an integer from 1 to 3,a is a number of value 2/q, andR4, R5, R6 and R7 independently of one another represent alkyl, cycloalkyl, aryl or aralkyl.
