Electrode material, for a lithium-ion-based electrochemical cell, containing primary particles of a Mn-containing spinel-type metal oxide selected from the group consisting of spinel-type lithium-nickel-manganese-oxide, spinel-type lithium-manganese-oxide, and mixtures thereof. Mn of the Mn-containing spinel-type metal oxide is partially substituted with a substitution-element selected from the group consisting of Si, Hf, Zr, Fe, Al, V and mixtures thereof and the primary particles are aggregated in order to form secondary particles, with the secondary particles having the shape of a microsphere.
