The present invention includes lithium manganese oxide spinel compounds having a low porosity, a high tap density and a high pellet density, and methods of preparing these compounds. In particular, the method comprises preparing a lithium manganese oxide with a spinel structure and having the formula: wherein:M1, M2, . . . Mk are cations different than lithium or manganese selected from the group consisting of alkaline earth metals, transition metals, B, Al, Si, Ga and Ge;X, Y, m1, m2, . . . , mk, each have a value between 0 and 0.2;Z has a value between -0.1 and 0.2; andX, Y, m1, m2, . . . mk are selected to satisfy the equation:
