The products have been characterized by X-ray diffraction, wet chemical analyses for lithium and oxygen contents, infrared spectroscopy, and thermogravimetric analysis to determine whether or not protons are incorporated into the lattice during the delithiation process. While the delithiation in aqueous acid medium leads to an incorporation of protons into the layered oxide lattice, the non-aqueous delithiation with NO2BF4 does not involve any proton insertion into the lattice. In contrast to the layered oxides, the chemical delithiation of spinel LiMn2O4 even in the aqueous acid medium does not involve any proton insertion into the lattice.
