High‐Entropy Oxides: High‐Entropy Oxides: Fundamental Aspects and Electrochemical Properties (Adv. Mater. 26/2019)

In article 1806236, Horst Hahn, Leonardo Velasco, Ben Breitung, and co-workers highlight developments in the area of high-entropy oxides, which have been the subject of significant interest recently. Entropy-dominated phase-stabilization effects and prospective applications in the field of electrochemical energy storage are discussed.
