摘要
The present invention refers to a redox-flow battery (1) comprising a positive compartment (10) comprising a positive electrode (11) and a catholyte, wherein said catholyte is an alkaline ferrocyanide solution; a catholyte reservoir container (12) connected in fluid communication with the positive compartment (10) through at least one conduct (13) and said container (12) comprising catholyte and a solid electroactive material (14), wherein said solid electroactive material is confined within the container and is selected from the group consisting of a metal oxide, a metal hydroxide, a metal oxyhydroxide or a combination thereof; a negative compartment (20) comprising a negative electrode (21) and an anolyte, wherein said anolyte is an alkaline solution; an anolyte reservoir container (22) connected in fluid communication with the negative compartment (20) through at least one conduct (23) and said container (22) comprising anolyte; and a power/load source (40). In addition, the present invention is directed to an energy storage system comprising at least one redox-flow battery (1) as defined above, to a method of storing electricity comprising providing a redox-flow battery (1) as defined above, a method of delivering electricity comprising providing a redox-flow battery (1) as defined above, to the use of the redox-flow battery (1) as defined above to store or deliver electricity and to the use of the redox-flow battery (1) as defined above in renewable energy and electromobility sectors.
