摘要	A new P2-structured oxide Na0.8Ni0.4Mn0.602was synthesized using a solid reaction method in whichNa2CO3, MnO2 and NiO were used as starting materials.This oxide has a high amount of electrochemically activeNi and exhibits good electrochemical intercalation behav-ior of Na ions, including good rate capability and goodcycle performance at both room temperature and elevatedtemperature. It displays two apparent voltage plateaus atabout 3.6 and 3.3 V, and its discharge capacity reaches92 mAh-g-l at 0.1C in the voltage range of 2.0-4.0 V. At1.0C, its discharge capacity reaches 85.3 mAh.g^-1. After80 cycles at different current rates, the as-prepared sampleexhibits good capacity retention. At elevated temperatureof 55℃, the discharge capacity remains the same at lowcurrent rate of 0.1C, but at high current rate of 1.0C, thedischarge capacity is a little lower than that at roomtemperature.
