The polytypes P2-Na0.62Ti0.37Cr0.63O2 and P3-Na0.63Ti0.37Cr0.63O2 with nearly the same composition and different layered structures are successfully synthesized, their sodium storage performance are systematically investigated and compared and the bridge between crystal structures, migration paths and electrochemical properties is well set up for the first time.
