Bi-phasic O3/P2 sodium layered oxides are leading candidates for next-generation batteries but rational control of the O3/P2 ratio remains challenging. Here, the O3/P2 ratio is tuned by using the average ionic radius of the transition metal layer, leading to materials with different characteristics.
