Abstract

Undoped lithiation of stoichiometric spinel using lithium hydride LiH up to the composition Li_2.25Mn₂O₄ was performed. A homogeneous material with a given Li: Mn ratio was obtained by mechanochemical activation with sequential annealing of a LiMn₂O₄–LiH mixture in a high-purity argon atmosphere and then in air or oxygen at 373–553 K.
