Abstract (en)

[origin: WO9900329A1] The invention relates to a method for producing mixed oxides with slightly variable electrochemical properties and spinel-type structures of formula (I): LixMeyMn2-yO4, in which Me is a metal cation from the II, III, IV, V and VI main groups or from the I, II, IV, V, VII or VIII subgroups of the periodic table of the elements, in particular a cation from the group of elements Al, Co, Cr, Fe, Ge, Mg, Nb, Ni, Sn, Ta, Te, V, W, Zn, and 0</=x</=2 and 0</=y<2. The invention also relates to their use in producing manganese dioxide electrodes for galvanic cells, electrochemical cells, secondary batteries, in particular for prismatic and round cells.
