High Entropy Materials for Energy Storage and beyond

Content of the lecture:

High entropy materials (HEMs) have gained tremendous attention over the past years. HEMs are multicomponent systems that contain five or more principal elements in near to equiatomic proportions in the same structure/sublattice. Materials are defined as HEMs having configurational entropies larger than 1.5 R which exclusively depends on the number and molar ratio of the incorporated elements in a random state. The family members of HEMs have been extended from high entropy alloys (HEAs) to high entropy oxides (HEOs), and other high entropy compounds. The disordering of atoms within the ordered crystal provides promising opportunities for achieving unprecedented combinations of phase stability with tailorable functional properties. To date, HEMs have emerged with great possibilities for various energy-related applications, such as energy storage, electrocatalysis, etc.
