Abstract: A method of preparing a positive active material is provided to save the production costs by not using inexpensive inert gas, to produce micro-sized particles with excellent crystallinity, and to cause no environmental contamination by using water as solven. A method of preparing a positive active material comprises the steps of: mixing a lithium precursor, transition metal precursor and phosphor precursor with a carbon precursor; after supplying the mixture with deionized water to a high pressure reactor(10), raising the temperature and pressure until they reach the supercritical water state in the high pressure reactor; after moving the materials synthesized by the supercritical water reaction in the high pressure reactor, to a cooling tank(20), cooling quickly while ejecting the synthesized materials, to grow the crystal to the circumference of the carbon precursor; and filtering the particles obtained from the crystal growth though a filter to obtain the C/LiMPO4 positive active material.
