Abstract
A supercapacitor is provided with a method for fabricating the supercapacitor. The method provides dried hexacyanometallate particles having a chemical formula AM1M2(CN).pHO with a Prussian Blue hexacyanometallate, crystal structure, where A is an alkali or alkaline-earth cation, and M1 and M2 are metals with 2+ or 3+ valance positions. The variable m is in the range of 0.5 to 2, x is in the range of 0.5 to 1.5, y is in the range of 0.5 to 1.5, and p is in the range of 0 to 6. The hexacyanometallate particles are mixed with a binder and electronic conductor powder, to form a cathode comprising AM1M2(CN).pHO. The method also forms an activated carbon anode and a membrane separating the cathode from the anode, permeable to A and A' cations. Finally, an electrolyte is added with a metal salt including A′ cations. The electrolyte may be aqueous.
