Abstract
A protected transition metal hexacyanoferrate (TMHCF) battery cathode is presented, made from AMFe(CN).mHO particles, where the A cations are either alkali or alkaline-earth cations, and M is a transition metal. In one aspect the cathode passivation layer may be materials such as oxides, simple salts, carbonaceous materials, or polymers that form a film overlying the AMFe(CN).mHO particles. In another aspect, the cathode passivation layer is a material such as oxygen, nitrogen, sulfur, fluorine, chlorine, or iodine that interacts with the AMFe(CN).mHO particles, to cure defects in the AMFe(CN).mHO crystal lattice structure. Also presented are TMHCF battery synthesis methods.
