Some performance characteristics of a Prussian blue battery

Neff (1978), Ellis et al. (1981), and Itaya et al,. (1982) have studied the thermodynamic and kinetic characteristics of the electrochemical oxidation and reduction of thin films of Prussian blue (PB) on various substrates. The present note has the objective to point out the feasibility of a Prussian blue battery, taking into account also the determination of some preliminary performance characteristics of a Prussian blue battery. It is shown that two half-cells could be combined to make a PB battery which, in the uncharged state, would consist of PB as both anode and cathode. One of the major problems encountered is the adherence of the PB deposit on the carbon substrate.
