<P>PROBLEM TO BE SOLVED: To provide a cathode structure prepared as a mechanical structure to enable high current density on one hand, and to provide high cycle durability even at a high number of cycles on the other hand. <P>SOLUTION: In the cathode structure of a lithium battery having a support structure (10) into which active materials (40) are introduced, the support structure has mutually parallel numerous protrusions (20), the protrusions (20) are joined to a support layer (30) to be integrally penetrated respectively on a side, the active materials (40) are arranged between the protrusions (20), frozen casting is applied to the parallel protrusions as suspension in water, and formed by continuously fixed particles. The active materials (40) are arranged on a surface of the protrusions between the sintered protrusions (20). <P>COPYRIGHT: (C)2011,JPO&INPIT |
