Battery comprising a coated iron anode

摘要

The present invention provides one with a battery having an iron anode, e.g., a Ni—Fe battery, having improved performance characteristics. The battery uses a particular electrolyte and/or battery separator. The resulting characteristics of efficiency, charge retention and cycle life are much improved over such batteries in the prior art.
