Two different high-entropy oxide materials were synthesized and studied as Li-ion battery anodes. They have different initial crystalline structures due to the presence of different inactive elements. Metal elements in these materials were studied over extended electrochemical cycling and found that the redox processes responsible for the electrode capacity are independent of the initial crystallographic structure.
Two different high-entropy oxide materials were synthesized and studied as Li-ion battery anodes. The two materials have the same active metal constituents but different inactive elements which result in different initial crystalline structures: rock salt for (MgFeCoNiZn)O and spinel for (TiFeCoNiZn)(3)O-4. Local structural studies of the metal elements in these two materials over extended electrochemical cycling reveal that the redox processes responsible for the electrode capacity are independent of the initial crystallographic structure and that the capacity is solely dependent on the initial random distribution of the metal atoms and the amount of active metals in the starting material.
