The elemental pegging effect in locally ordered nanocrystallites of high-entropy oxide enables superior lithium storage

In this work, a high entropy oxide, (Mn 0.23 Fe 0.23 Co 0.22 Cr 0.19 Zn 0.13 ) 3 O 4 , is prepared as anode material for lithium-ion batteries. It shows excellent rate and cycling stability due to the Zn pegging effect in the locally ordered nanocrystallites.
