Na0.67Cr0.33Mg0.17Ti0.5O2 with a P2-type layered structure has been synthesized and examined as a negative electrode material for rechargeable sodium batteries. The layered oxide delivers a reversible capacity of >90 mA h g-1, which corresponds to >95% of the theoretical capacity with excellent cyclability for >450 cycles.
