摘要： PROBLEM TO BE SOLVED: To provide raw fine particles, a manufacturing method for them and a positive electrode material capable of improving discharging capacity, cycle characteristics and rate characteristics of a positive electrode material of a lithium secondary battery. SOLUTION: As for raw fine particles for a positive electrode of a lithium secondary battery having a separator disposed between a negative electrode of a carbon material and a positive electrode of a spinel lithium manganese oxide material and filled with a nonaqueous electrolyte, the raw fine particles of the spinel lithium manganese oxide are obtained through a sieve with a desired mesh, a difference between the rate of the residual raw lithium material after sieving/manganese (a value obtained by dividing the number of lithium atoms by the number of manganese atoms) and the rate of the lithium material passed through the sieve/manganese is set at 0.02 or less to obtain the raw fine particles for the positive electrode of the lithium secondary battery. After the raw fine particles are decided acceptable or not, an only acceptable raw fine particles are used in a manufacturing method for the positive electrode of the lithium secondary battery and for the positive electrode.
