STABILIZATION OF BATTERY ELECTRODES

摘要

An electrochemical apparatus (e.g., a battery (cell)) including an aqueous electrolyte with electrode stabilizing additives and one or two electrodes (e.g., an anode and/or a cathode), one or both of which is a Prussian Blue analogue material of the general chemical formula AxPy[R(CN)6- jLj]z.nH2O, where: A is a cation; P is a metal cation; R is a transition metal cation, L is a ligand that may be substituted in the place of a CN- ligand; 0≤x≤2; 0 < y≤4;0 < z≤1; and 0≤n≤5 with the electrolyte including an additive to reduce capacity loss of the electrode(s).
