This research not only helps us deeply understand the Li ion diffusion mechanism in oxide materials, but also provides the new insight in designing the Li superionic conductors within the vast chemical space of fcc-type oxides. It is noted that this design scheme is based on the simultaneous adjustment of the size of diffusion path and the content of Li ions. In fact, previous study has shown that Li ions can still achieve rapid diffusion even under the low Li content (without the synchronized diffusion). Therefore, mastering the coordination between the above two effects holds the key to design Li superionic conductors.
