    • The present invention provides a sodium secondary battery capable of reducing the amount used of a scarce metal element such as lithium and cobalt and moreover, ensuring a larger discharge capacity after repeating charge/discharge as compared with conventional techniques, and a mixed metal oxide usable as the positive electrode active material therefor. The mixed metal oxide of the present invention comprises Na, Mn and M1 wherein M1 is Fe or Ni, with a Na:Mn:M1 molar ratio being a:(1-b):b wherein a is a value falling within the range of more than 0.5 and less than 1, and b is a value falling within the range of from 0.001 to 0.5. Another mixed metal oxide of the present invention is a mixed metal oxide represented by the following formula (1): NaaMn1-bM1bO2 (1) wherein M1, a and b each have the same meaning as above. The positive electrode active material for sodium secondary batteries of the present invention comprises the mixed metal oxide above.
    • 本发明提供一种钠二次电池,其能够减少诸如锂和钴之类的稀有金属元素的使用量,此外,与常规技术相比,确保了重复充电/放电后的放电容量更大,并且可用作 正极活性物质。 本发明的混合金属氧化物包括Na,Mn和M1,其中M1是Fe或Ni,Na:Mn:M1的摩尔比为a:(1-b):b其中a是落在 大于0.5且小于1,b为0.001至0.5的范围内的值。 本发明的另一种混合金属氧化物是由下式(1)表示的混合金属氧化物:NaaMn1-bM1bO2(1)其中M1,a和b各自具有与上述相同的含义。 本发明的钠二次电池用正极活性物质包含上述混合金属氧化物。
