PROBLEM TO BE SOLVED: To provide a positive electrode body which uses LiCoO2 as its positive electrode active material and by which a lithium secondary battery having an improved charge-discharge cycle characteristic can be manufactured. SOLUTION: This positive electrode body for a lithium secondary battery has a positive electrode active material composition layer which is formed on one surface or both surfaces of a collector, and for which the content of lithium hydroxide is 0.4 wt.% or less, preferably, 0.1 wt.% or less, the content of water is 500 ppm or less, preferably, 300 ppm or less, and contains LiCoO2 for its positive electrode active material as a main ingredient. It is suitable for manufacturing a long life lithium secondary battery for a variety of electric apparatuses, in particular, portable appliances. |
