Abstract Scope |
Surfaces and interfaces in ionic ceramics play a pivotal role in defining the transport limitations in many of existing and emerging applications in energy-related systems, including fuel cells, rechargeable batteries, as well as electronics such as those found in semiconducting, mixed ionic, ferroelectric, and piezotronic applications. By starting from a thermodynamically consistent phase field formulation, the metal-insulator transition in polycrystalline LiCoO2 is presented. Effects such as the grain boundary lithium segregation, interfacial misorientation, and the size of the abutting grains are assessed. Regimes of behavior are identified. |
