For successful development of novel rechargeable batteries, considerable efforts should be devoted to identifying suitable cathode materials that will ensure a proper level energy output, structural stability, and affordable cost. Among various compounds explored as electrode materials, analogues minerals–natural stable inorganic solids–occupy prominent place. The largest number varieties phosphate minerals occurs in rare metal granite pegmatites, many which contain transition metals...
