<P>PROBLEM TO BE SOLVED: To provide a power storage device using an electrode material having a large capacity. <P>SOLUTION: First heat treatment is performed on a mixture of a compound containing lithium, a compound containing a metal element selected from manganese, iron, cobalt, and nickel, and a compound containing phosphorus. A cleaning step is performed on the mixture subjected to the first heat treatment. Second heat treatment is performed on the mixture subjected to the cleaning step, to form a lithium phosphate compound. With the use of the lithium phosphate compound, an electrode is formed. Thus, the electrode material having a large capacity can be obtained. The power storage device having a large capacity can be obtained using the electrode material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
