A redox battery with at least one cell is disclosed, in which a flow of electrolyte or electrolyte solution surrounds or flows through two electrodes, said electrodes being separated by a membrane. Each electrode is provided with a separate electrolyte circuit and both electrolyte solutions contain the same metal for the redox reaction which has at least two oxidation levels. According to the invention, an economical production and long-term constant and reliable operation may be achieved by having all the metal used for the redox reaction present in the system in only two oxidation levels and approximately half thereof is in a complex compound with a ligand and half in a complex compound with another substance. An electrolyte solution which may be economically produced in large amounts, the handling of which does not require particular precautions and which guarantees a secure, constant and economical operation is characterised in that half of the metal used for the redox reaction is in a complex compound with a ligand and half in a complex compound with another substance. |
