Electrochemistry of iodide in propylene carbonate. 1. Cyclic voltammetry monitored by optical spectroscopy.

Although the electrochemistry of very active metals in nonaqueous solvents has received much attention, the development of a practical electrowining process or a long-lived battery also requires the development of compatible anodic reactions in these solvents. Replacing water with stable aprotic solvents can often result in changes of several orders of magnitude in the solubility of salts, conductivity of solutions, and stability of intermediates, Thus even simple, well-characterized reactions in aqueous media show marked differences in strong donor solvents.
