Redox flow-batterier (RFB''er) er genopladelige batterier, som generelt er baseret på to flydende elektrolytter. Disse elektrolytter indeholder redoxarter i form af opløste salte, der bærer den elektriske ladning. En RFB består af en central elektrokemisk celle (eller stak) og af to lagertanke, der hver indeholder en af elektrolytterne.
That arrangement addresses the two major challenges with flow batteries. First, vanadium doesn''t degrade. "If you put 100 grams of vanadium into your battery and you come back in 100 years, you should be able to recover 100 grams of that vanadium — as long as the battery doesn''t have some sort of a physical leak," says Brushett.
