TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The method (M1) further involves: adjusting a final pH of at least one of first solution, second solution or complexcelle; and applying a coating to the powder. The gas is introduced into the first solution at a rate sufficient to increases a volume of the first solution by at least 5%. The gas is introduced into the first solution at a rate of at least one liter of gas per liter of first solution per minute. The complexcelle is formed at a temperature of not greater than 100 degrees C. The complexcelle is dried at not greater than 350 degrees C by spray drying, freeze drying, tray drying or evaporation drying method. The dried powder is calcined at 350-3000 degrees C in apparatus selected from box furnace, a rotary calciner, a fluidized bed calciner and a spray pyrolyzer. The second solution is added to the first solution through a tube having an inner diameter of at least 2 cm. The method forms a powder that has microstructure or nanostructure, which looks like e.g. a nanocroissant, nanorose, and nanohydrangea. Preferred Components: The first diffuser or the second diffuser is selected from porous ceramic, a tube, a membrane and a dome diffuser. The first or second agitator comprises concentric wires, or at least one blade that rotates on a shaft and on a blade axis. The first or second agitator has a mixing speed of at least 100 revolutions per minute (rpm). The tube further comprises at least one of an atomizer, sprinkler or nozzle. The gas is selected from air, carbon dioxide, methane, SF6, HF, HCl, NH3, propane, O2 and inert gas. The first solution comprises up to 30 wt.% of the first salt of Mj. The second solution comprises up to 30 wt.% of the second salt of Xp. The salt is selected from chlorides, hydroxides, nitrates, phosphates, oxalates, carbonates, acetates, sulfates, hydroxycarbonates, hydroxyl phosphates, hydroxysilicates and silicates. The first solution comprises up to 30 wt.% of the first salt of Mj. The powder further comprises a dopant that is present in an amount of up to 10 wt.% of the lithium metal oxide. The coating is selected from an organic compound and an inorganic compound. The coating comprises carbon.    TECHNOLOGY FOCUS - METALLURGY - Preferred Components: The dopant is selected from alkali or alkaline earth metals, Group III A elements, Group IV A elements and transition metals (preferably cobalt, aluminum and gadolinium).
