    does someone knows the cost of the vanadium salts being used to make the ion solution? How toxic is the solution?

    So filling stations would simply replace their gasoline tanks with lithium polysulfide tanks and big charging stations. A car pulls in, the spent liquid in the car is pumped out and fresh, charged liquid pumped in and it's refueled. The station then just recharges the fuel for the next customer. Sounds great, but the best laid plans ...

    Toxicity on experimental animals :
    Vanadium compounds are acutely toxic by most routes of exposure,
    in most species. In general, the toxicity of vanadium compounds increases
    with the Oxidation State. The rabbit and guinea pig are more sensitive than
    the rat and mouse. Repeated administration of vanadium compounds
    produces changes in protein metabolism, lipid profile, enzyme activities,
    reproductive activities, and other metabolic actions. Due to poor absorption
    from the gastrointestinal tract, the metal is not very toxic for human beings
    when ingested.
    Toxicity on human beings :
    In the past, vanadium compounds were prescribed as therapeutic
    agents for anaemia, chlorosis, tuberculosis and diabetes. Vanadium was also
    used as an antiseptic, a spirochetocide and as a tonic. Clinical picture of
    poisoning shows a broad spectrum of toxic effects of vanadium on the
    respiratory, circulatory and central nervous systems, the digestive organs,
    kidneys, and skin (Table 2). Vanadium poisoning in humans can be
    diagnosed on the basis of a history of exposure, the clinical picture, a green
    tongue (due to the hexa-aqua ion), and measurements of vanadium levels
    in blood cells, plasma and urine. The value of various tests of the secondary
    metabolic effects of poisoning is disputed. Dimercaprol and ascorbic acid
    may have value in the treatment of poisoning in human beings. There are
    no adequate epidemiological studies of mortality in occupationally exposed
    populations.
