PROBLEM TO BE SOLVED: To provide Li 5 FeO 4 useful as a positive electrode and other materials of a lithium ion secondary battery. A carbon-coated Li 5 FeO 4 containing a carbon film covering the surface of the the Li 5 FeO 4 Li 5 FeO 4 . Carbon-coated Li 5 FeO 4 having a BET specific surface area in the range of 1 to 12 m 2 / g, and excellent conductivity can be obtained by coating a carbon film, and carbon-coated Li can exhibit sufficient capacity as a positive electrode material 5 FeO 4 . Method of producing no compound by heating a first solid inorganic material and another second solid inorganic material, sucrose fatty acid, fatty acid salt, fatty acid amide, N, N'-ethylenebis fatty acid amide, fumaric acid The manufacturing method of the inorganic compound which adds the organic additive selected from alkyl ester alkali metal salt or hardened oil, and the said heating temperature is more than the temperature which the said organic additive vaporizes or decomposes. [Effects] The specific surface area of carbon-coated Li 5 FeO 4 and the characteristics of Li 5 FeO 4 can be controlled by the amount of the organic additive added. [Selected figure] Figure 1 |
