Inventors include Isosaari, Eveliina; Rsnen, Samuli; Blangero, Maxime; and Agyemang, Daniel Adjei.

The application for the patent was published on July 10, 2026, under issue no. 28/2026.

Abstract: The present invention concerns material comprising hydroxide or oxyhydroxide of at least one or more metal elements, and a cathode active material for lithium-ion secondary batteries. The present invention relates to a manganese-containing precursor for cathode active material for secondary batteries, said precursor comprising M and element oxygen, wherein M compress Ni in a content x, wherein 0.0 = x = 50.0 mol%, relative to M, Mn in a content y, wherein 50.0 = y = 90.0 mol%, relative to M, Co in a content z, wherein 0.0 = z = 40.0 mol%, relative to M, at least one element selected from the group consisting of Al, Ti, V, Mg, Cr, Ca, Zr, Nb, Mo, Hf, Ta, and W, in a content t, 0.0=t= 10.0 mol%, relative to M; wherein x, y, z, and t are measured by ICP-OES; and wherein x+y+z+t is 100.0 mol%; and wherein the manganese-containing precursor has a tap density, TD, of at least 1.65 g/cm3 and a ratio of a specific surface area, SSA, to the tap density, SSA/TD, of at least 12.00, expressed in unit (m2* cm3)/g2.
