Composite metal oxide and sodium rechargeable battery |
| abstract |
Disclosed is a sodium rechargeable battery that can reduce the amount of lithium used and has a higher discharge capacity retention upon repetition of charge and discharge than the conventional sodium rechargeable battery. Also disclosed is a composite metal oxide usable as a positive electrode active material for the sodium rechargeable battery. The composite metal oxide comprises Na and M1, wherein M1 represents three or more elements selected from the group consisting of Mn, Fe, Co, and Ni, and has a Na : M1 molar ratio of a : 1 wherein a is a value in a range of more than 0.5 and less than 1. Further disclosed is a composite metal oxide represented by formula (1). Still further disclosed is a positive electrode active material for a sodium rechargeable battery, comprising the composite metal oxide represented by NaaM1O2 (1) wherein M1 and a each are as defined above. |
