Abstract
The cycling stability and capacity of li-ion rechargeable batteries are improved by the use of lithium manganese oxy-fluoride electrode component intercalation materials having the general formula, Li.sub.1+x M.sub.y Mn.sub.2-x-y O.sub.4-z F.sub.z, where M is a transition metal, e.g., Co, Cr, or Fe, and x.ltoreq.0.4, y.ltoreq.0.3, and 0.05.ltoreq.z.ltoreq.1.0.
