dont know about the Vanadium Cell but if u know the chem of the lead acid cell why not go with that and a button cell, with the chemistry being almost identical (the cathode is the only different bit) you can save memorising something different :)

hmm let's see --

Cathode u have VO2^+ in a VO^2+ solution.

Graphite Felt between em.

Anode u have V^2+ in a V^3+ solution.

Overall Reaction: V^2+ + VO2^+ + 2H^+ <---> V^3+ + VO^2+ + H2O

So the electrolytes are VO^2+ solution and V^3+ solution?
