Provided are a method for preparing a uniform nano-sized composite compound of a metal oxide and carbon, and a technique for using the manufactured composite compound for a device such as a battery. A nanocomposite compound of an oxide and carbon formed by mixing and thermally decomposing a metal compound, a hydrate thereof, or a solution thereof and carbon. The above nanocomposite compound using two or more metal compounds, hydrates, or solutions thereof. The above nanocomposite compound, wherein the atmosphere when heating is controlled by the target compound. The above nanocomposite compound, wherein the composition, shape and / or particle size are controlled by using carbon materials having different specific surface areas. Devices such as lithium secondary batteries and capacitors using the above nanocomposite compounds. [Selection diagram] Fig. 1 |
