We deduce that a change in the cubic lattice parameters of the LiCo x Mn2- x O4 compounds during Li insertion depends on the solid-state redox reactions; in particular, a smaller dimensional change is observed for the Co3+/Co4+ redox reaction, while a larger change is observed for the ...
This concept focuses on the polarizability of the metal ion, which is approximated using the ionic potential (electrostatic binding) as defined by z/r (z = charge, r = ionic radius) and ionization potential (In) of M to Mn+ (electron acceptor power). Polarizability reflects the ability of...

A shrinkage of 0.027 in the unit cell size per 0.01 decrease in the ionic radius of the trivalent cations was determined in spinels having the same divalent cation and cation arrangement when the trivalent cations form the same type of bonds.The half-occupation of the 3d orbits in Mn2+ and...
