Magnesium-substituted birnessite and zinc chalcophanite have been synthesized through a novel procedure based on a combination of coprecipitation and metal ion intercalation techniques. The materials showed very promising performance as hosts for lithium intercalation. Upon galvanostatic discharge, Mg-birnessite and Zn-chalcophanite composite cathodes were able to intercalate > 2 equiv of lithium per mole.
