Lithium secondary battery and cathode of the lithium secondary battery |
摘要 |
To provide a lithium secondary battery which has high capacity while maintaining excellent cycle characteristic. The lithium secondary battery cathode of the present invention includes a cathode collector formed of a conductive substance, and a cathode active material layer formed of a sintered lithium composite oxide sheet. The cathode active material layer is bonded to the cathode collector by the mediation of a conductive bonding layer. A characteristic feature of the present invention resides in that the cathode active material layer has a thickness of 30 µm or more, a mean pore size of 0.1 to 5 µm, and a voidage of 3% or more and less than 15%. |
