P2-Na0.6[Cr0.6Ti0.4]O2 cation-disordered electrode for high-rate symmetric rechargeable sodium-ion batteries

Abstract Most P2-type layered oxides exhibit Na + /vacancy-ordered superstructures because of strong Na + –Na + interaction in the alkali metal layer and charge ordering in the transition metal layer. These superstructures evidenced by voltage plateaus in the electrochemical curves limit the Na + io... View More
