a Schematic representation of the spinel structure of LiMn2O4, illustrating the arrangement of Li in tetrahedral sites (8a), Mn in octahedral sites (16d), and oxygen ions in the cubic close-packed framework (32e). Adapted from Berg et al.151; b Modified spinel structure of Li1.33Mn1.67O4, showing increased Li⁺ occupancy in the 16c and 16d sites. Adapted from Murodjon et al.152.
