PURPOSE:To enhance the discharge capacity and Coulomb efficiency of an organic elecrtrolyte battery by using Li/Co composite oxides having a crystalline structure strongly oriented in the [003] plane and excellent in the Li ion occlusion/emission performance. CONSTITUTION:Co compounds and Li compounds are mixed and baked, and again baked. Such Li/Co composite oxide (LiC0O2) is synthesized that the intensity of the diffraction peak discerned around where 2theta is 53 deg. is no more than 9% of the intensity of the diffraction peak perceived around where 2theta is 22 deg. according to the X-ray diffraction test using cobalt Kalpha rays. This composite oxide is used to pos. electrode active substance. In this substance the [003] plane of the crystal has grown remarkably. This enables enhancing the discharge capacity of battery and its Coulomb efficiency at the time of charging and discharging. |
