TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preparation: No preparation method is given. Preferred Components: (I) further comprise 0-10 wt.% of a dopant, and a coating. The dopant consists of alkali or alkaline earth metals, group III A, group IV A and transition metals. (I) comprise lithium metal oxides, calcium phosphates, lithium aluminosilicate, lithium aluminates, lithium metal phosphates, lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide, and lithium mixed oxides of cobalt, nickel and manganese. The coating comprises: alkali or alkaline earth metals, group III A and IV A and transition metals; and an organic or another inorganic compound. The coating is a nanolayer, and comprises carbon or a carbon-containing compound. (I) are nanostructures. The nanostructure is a nanocroissant, nanorose or nanohydrangea. (I) have a particle size of less than 1 mu m and a surface area of at least 1 m2/gm. The battery further comprises a cathode comprising a lithium salt of at least one of nickel, manganese, cobalt, titanium, magnesium, or zinc. The lithium salt is a lithium nickel manganese cobalt salt of formula (Li2-x-y-zNixMnyCozO2). The battery has a capacity of 80 mA-hour/g after 500 cycles at discharge rate of 1 C at room temperature from 4.2 V to 3 V, or a capacity of 150 mA-hour/g after 500 cycles at discharge rate of 1 C at room temperature from 4.6 V to 2.5 V.x+y+z = 1, where one of x, y or z is not zero. EXAMPLE - 46.2 g of Lithium carbonate was added into a reactor containing 1 l of deionized water. Carbon dioxide gas was allowed to flow through the reactor using a gas tube bubbler on a side or a diffuser bubbler at a bottom of a reactor vessel. 120.2 g of Cobalt carbonate and 1 l of deionized water were added into a second reactor equipped with a tube bubbler or a diffuser bubbler. Carbon dioxide gas was allowed to flow through the bubblers. 250 ml of Ammonia was added to the second reactor. After a given amount of time to allow dissolution or vigorous mixing of the corresponding reactants, the cobalt solution was pumped into the lithium solution at a rate of 1 l/hour. The resulting mixture was passed through a spray dryer. The outlet temperature was adjusted to 115 degrees C. The dried powder was collected and placed in a sagger and fired in a box furnace in air for 5 hours at 900 degrees C to obtain lithium cobalt oxide.
