    Abstract: A hydrothermal electrochemical synthetic method of lithium cobalt oxide(LiCoO2) is provided to improve the crystallinity and adhesiveness so as to lower the reaction temperature, to eliminate the use of an autoclave, to reduce the reaction time by applying pulse electric current, and to solve dissolution problem in the cathode, thereby providing prolonged use thereof. The hydrothermal electrochemical synthetic method of lithium cobalt oxide comprises an addition of saccharin to an aqueous solution where a lithium salt and a cobalt salt or a cobalt powder are dissolved in water, and an application of pulse electric current during the hydrothermal electrochemical reaction, wherein each of the lithium salt and the cobalt salt is selected from hydroxide, nitrate, acetate, chloride, sulfate, oxalate and mixtures thereof, the saccharin is used in an amount of 1-50ppm, and oxygen gas is bubbled into the aqueous solution by using a bubbler which is possible to be introduced and removed during the synthetic process.
