Elevated-temperature creep strength of LiFeO2, LiCoO2 and NiO-5(at.%)Li2O

Abstract

Abstract The elevated-temperature creep strength of several alternative cathode materials (LiFeO 2 and LiCoO 2 , both pure and doped) for potential use in molten carbonate fuel cells was compared to the currently used Li (1–5 at%)-doped NiO. It was observed that at 1000 °C, LiFeO 2 , LiFeO 2 -12.5 at% NiO, LiFeO 2 -9 at% MgO and LiCoO 2 have a lower strength than NiO-5 at% Li 2 O.
