Abstract: There is produced a Li-containing silicon oxide powder containing a crystallized lithium silicate that is mostly water-insoluble Li 2 Si 2 O 5 and containing little crystalline Si. This object is attained through the mixing of a lower silicon oxide powder represented by a compositional formula SiO x (0.5
