High-entropy battery materials: Revolutionizing energy storage
The significance of high–entropy effects soon extended to ceramics. In 2015, Rost et al. [21], introduced a new family of ceramic materials called "entropy–stabilized oxides," later known as "high–entropy oxides (HEOs)".They demonstrated a stable five–component oxide formulation (equimolar: MgO, CoO, NiO, CuO, and ZnO) with a single-phase crystal structure.
