Are we allowed to do Lead Acid Cell vs Vanadium Cell? (1 Viewer)

[.ben]

I just need to confirm because i thought they were both secondary cells? thanks

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

ok then, for the vanadium cell, what is the electrolyte?

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?
