The team of Dr.
Layered oxides have periodic layered structures and two-dimensional ion transport channels, and are a type of intercalation compound that has been studied earlier
2 6 x 2 2 6
It is an important research direction to explore the factors affecting the formation of the two configurations of sodium ion layered oxides

cation x 2 cation (OMO) (O-Na-O) 1/3 2/3 2 1/3 1/6 1/2 2 5/6 5/18 13/18 2
This research provides a new method for the design of layered oxide structure, and confirms the effectiveness of the method with experiments, laying a scientific foundation for the design and preparation of layered oxide cathode materials for low-cost, high-performance sodium ion batteries
