POSITIVE-ELECTRODE COMPOSITION FOR A NONAQUEOUS-ELECTROLYTE SECONDARY BATTERY AND METHOD FOR MANUFACTURING A POSITIVE-ELECTRODE SLURRY USING SAID POSITIVE-ELECTRODE COMPOSITION

A positive electrode composition that has improved output power characteristics and low costs, and is also easily handled upon production of a positive electrode, and exhibits an improved yield is provided. [0002] A positive electrode composition comprising a positive electrode active material composed of a lithium transition metal complex oxide represented by the general formula LiNiCoMLO (wherein 0 ≤ x ≤ 0.50, 0.30 ≤ y ≤ 1.0, 0 < z ≤ 0.5, 0 ≤ w ≤ 0.1, 0.30 < y + z + w ≤ 1, M represents at least one kind selected from Mn and Al, and L represents at least one kind of an element selected from the group consisting of Zr, Ti, Mg and W), and additive particles composed of acidic oxide particles is used for positive electrode.
