Abstract:The corrosion resistance of the current collector seriously affects the capacity and stable cycling of liquid metal batteries (LMBs). This investigation explores the interface reactions and electrochemical properties between Ni-Fe and Fe foam negative current collectors and the liquid negative metals in Na|NaCl-CaCl2|Zn LMB. The results elucidate that Ni-Fe foam is erroded and the corrosion products of Ca2Ni5, and Ni2Zn11 are formed on the surface. It accelerates the deposition of Zn and the dissolution of Ni-… Show more
