For electric car applications, the nickel-iron storage battery can offer up to 75% higher energy density when compared to the lead-acid battery. However, because of the ease of hydrogen evolution at the iron anodes, this battery suffers from poor charging efficiency and a high self-discharge rate. Both factors degrade energy efficiency. The proposed research will examine a range of electrolyte additives to determine their effectiveness in inhibiting the energy-wasting hydrogen evolution reaction on iron electrodes.

对于电动汽车应用，与铅酸电池相比，镍铁蓄电池可以提供高达75%的能量密度。然而，由于铁阳极容易放氢，这种电池存在充电效率低和自放电率高的问题。这两个因素都会降低能源效率。这项拟议的研究将检查一系列电解液添加剂，以确定它们在抑制铁电极上浪费能源的放氢反应方面的有效性。
