POSITIVE-ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, METHOD FOR PRODUCING SAID POSITIVE-ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY USING SAID POSITIVE-ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
The purpose of the present invention is to provide a positive-electrode active material for non-aqueous electrolyte secondary batteries that is capable of achieving both a high capacity and a high output. This positive-electrode active material contains a lithium-nickel composite oxide represented by the general formula: Li b Ni 1-x-y Co x M y O 2 wherein M represents at least one element selected from Al, Ti, Mn and W, b is 0.95 ‰¤ b ‰¤ 1.03, x is 0 < x ‰¤ 0.15, y is 0 < y ‰¤ 0.07, and x and y is x+y ‰¤ 0.16, wherein c-axis length of the lithium-nickel composite oxide is 14.185 angstrom or greater as determined by a Rietveld analysis of X-ray diffraction. |
