The Synergistic Effect of MoS₂ and NiS on the Electrical Properties of Iron Anodes for Ni-Fe Batteries.

ABSTRACT: In this paper, a series of Fe₃O₄/MoS₂/NiS composite electrodes were synthesized by a simple coprecipitation method. The influence of different ratio additives (MoS₂ and NiS) on the performance of iron anodes for Ni-Fe batteries was systematically investigated. In this paper, the mixed alkaline solution of 6 mol/L NaOH and 0.6 mol/L LiOH was used as electrolyte, and sintered Ni(OH)₂ was used as counterelectrode. The experimental results show that the MoS₂ and NiS additives can effectively eliminate the passivation phenomena in iron electrodes, reduce the electrode polarization, and increase the reversibility capacity. As a result, the Fe₃O₄/MoS₂/NiS composite electrodes exhibit a high specific
