High-Entropy Oxides(FeCoNiCrMn)(3)O-4DFTLithium storage mechanismMORPHOLOGYHigh-Entropy Oxides (HEOs) are a novel type of perspective anode materials for lithium ion batteries (LIBs), owing to their stable crystal structure and high theoretical capacity. However, the understanding of their intrinsic ...
High entropy oxides (HEOs) with chemically disordered multi-cation structure attract intensive interest as negative electrode materials for battery applications. The outstanding electrochemical performance has been attributed to the high-entropy stabilization and the so-called ‘cocktail effect’. However, th...
we synthesized the high-entropy oxides[(FeCoNiMnV)_(x)O]and used them as efficient OER catalysts.A simple oil-phase method was used to synthesize(FeCoNiMnV)_(x)O.The catalytic performances of the(FeCoNiMnV)_(x)O catalysts were modified by tuning the reaction temperature.The optimized(FeCoNi...
