Positive electrode active material for secondary battery and method for manufacturing the same |
| abstract |
An object of the present invention is to provide a positive electrode active material capable of achieving high energy density as a secondary battery by increasing the density and positive electrode density of the positive electrode active material powder itself. As a positive electrode active material for a secondary battery, contains one or two or more compounds represented by the formula Li[Li x Mn y M (1-xy) ]O 2 , and the positive electrode active material is a secondary particle in which primary particles are aggregated. Formed, the powder pressing density when the positive electrode active material powder is pressed at a pressure of 62 MPa is 2.7 g/cm 3 or more, and the crystallite size obtained from the diffraction line 104 by X-ray diffraction of the positive electrode active material is 20 nm It is achieved by the positive electrode active material for secondary batteries which is 30 nm or more and less. |
