The nickel/iron battery

Abstract The nickel/iron battery is a rechargeable electrochemical power source with certain special advantages. It has good scope for traction applications. The present state-of-art advantages, limitations, and uses of the nickel/iron battery, along with its electrochemical characteristics, are outlined in this review. Various methods available for fabricating both the negative iron and the positive nickel oxy-hydroxide (NiO·OH) electrodes, as well as the electrochemical characteristics of these electrodes, are discussed.
