| Abstract Scope |
The tremendous growth of the Li-ion battery industry is requiring the design of novel electrode materials that can be synthesized from mixtures of relatively earth-abundant metals. Rather than achieving their properties from judicious choice of a single element, these novel materials derive their properties from the synergistic interaction between multiple metal cations. To achieve high capacity and high Li-transport rate as cathode materials these materials require very careful design of the cation short-range order. I will review how short-range order controls Lithium mobility in Disordered Rocksalt Cathodes (DRX) and how it can be modified through synthesis, compositional choices, and high-entropy designs. Controlled growth of medium-range order upon cooling from high-temperature has recently led to the development of materials with very high energy density and high-rate capability.
In ionic conductors, high entropy concepts can be used to create high mobility in otherwise poor conductors by creating percolating pathways of locally distorted environments. |
