摘要：

Layered Na 0.85Li 0.17Ni 0.21Mn 0.64O 2 is synthesized and evaluated as a cathode in Na batteries. The resulting P2 crystal structure allows for single-phase reversible Na intercalation reaction demonstrating 100 mAhg -1. The cathode can be discharged with high rate (65 mAhg -1 at 25 C rate). The presence of Li and the electronic ordering of Ni(II)/Mn(IV) in the transition metal layer is responsible for material stability. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
