Abstract: 
With the increasing demand for safer, more stable, and energy dense batteries, investigations into single crystal layered oxide cathodes have gained momentum. However, translating considerations from polycrystalline to single-crystalline particles and their ensembles is not one-to-one. Lithium diffusion path length, surface, dopants and coatings, as well as the synthetic methods used take on different dimensions for single-crystalline particles. In this concept article, we review key considerations that must be made when developing well-performing single crystal layered oxide cathodes. We discuss how diffusion limitations can affect material stability in addition to how improvements to diffusivity can act as a method to simultaneously improve rate capability and surface stability. In addition, we briefly discuss how the unique feature of faceting and the synthetic design space for single-crystalline particles should be conceptualized.
