Abstract

Provided is a secondary battery positive electrode that can improve the rapid charge and discharge and can increase the heat resistance. Also provided are a secondary battery comprising the secondary battery positive electrode, and a method for producing the secondary battery positive electrode. The secondary battery positive electrode comprises an aluminum material, a positive active material layer comprising a lithium-containing metal oxide as a positive active material, and formed on the surface of the aluminum material, and an intervening layer comprising aluminum and carbon, and formed between the aluminum material and the positive active material layer. A secondary battery positive electrode is produced by forming a positive electrode active material layer comprising a lithium-containing metal oxide as a positive electrode active material on the surface of an aluminum material, and heating the aluminum material with the positive active material layer formed thereon in a space containing a hydrocarbon-containing substance.
