Abstract
Provided is a positive electrode material for a lithium ion secondary battery, including a crystallized glass powder including an olivine-type crystal represented by General Formula LiMxFe1-xPO4 (0≦x<1, M represents at least one kind selected from Nb, Ti, V, Cr, Mn, Co, and Ni), in which the crystallized glass powder has an amorphous layer in its surface.
Claims14
A positive electrode material for a lithium ion secondary battery, comprising a crystallized glass powder comprising an olivine-type crystal represented by General Formula LiMxFe1-xPO4 where a relationship of 0≦x<1 is established and M represents at least one kind selected from Nb, Ti, V, Cr, Mn, Co, and Ni, wherein the crystallized glass powder has an amorphous layer in its surface.
A positive electrode material for a lithium ion secondary battery, comprising an olivine-type crystal represented by General Formula LiMxFe1-xPO4 where a relationship of 0≦x<1 is established and M represents at least one kind selected from Nb, Ti, V, Cr, Mn, Co, and Ni, wherein the positive electrode material comprises a magnetic particle at 1000 ppm or less.
