中文摘要：

Layered oxides of P2-type Na0.68Cu0.34Mn0.66O2, P2-type Na0.68Cu0.34Mn0.50Ti0.16O2, and O’3-type NaCu0.67Sb0.33O2 were synthesized and evaluated as cathode materials for room-temperature sodium-ion batteries.The first two materials can deliver a capacity of around 70 mAh/g. The Cu2+is oxidized to Cu3+during charging, and the Cu3+goes back to Cu2+upon discharging. This is the first demonstration of the highly reversible change of the redox couple of Cu2+/Cu3+with high storage potential in secondary batteries.

英文摘要：

Layered oxides of P2-type Nao.68Cuo.34Mno.6602, P2-type Nao.68Cuo.34Mno.50Tio.1602, and O＇3-type NaCuo.67Sbo.3302 were synthesized and evaluated as cathode materials for room-temperature sodium-ion batteries. The first two materials can deliver a capacity of around 70 mAh/g. The Cu2＋ is oxidized to Cu3＋ during charging, and the Cu3＋ goes back to Cu2＋ upon discharging. This is the first demonstration of the highly reversible change of the redox couple of Cu2＋/Cu3＋ with high storage potential in secondary batteries.
