Abstract: Disclosed herein is a particulate material of the composition LiaMgb)i+x(NicM1dM2e)1−xO2 where M1 is selected from Ti, Zr, Nb, Mo, and W, and combinations of at least two thereof; M2 is selected from Al, Co, Mn, and combinations of at least two thereof; a:b is in the range of from 100:1 to 400:1, and a+b=1; c:d is in the range of from 40:1 to 250:1, and c:e is in the range of from 12:1 to 50:1; and c+d+e=1; the total molar ratio of (Li+Mg) to (Ni+M1+M2) is in the range of from 1:1 to 1.05:1; and 0.00≤x≤0.05, where the particulate material has an average particle diameter (D50) in the range of from 2 to 20 μm.
