<P>PROBLEM TO BE SOLVED: To provide a collector of a positive electrode for a lithium based secondary battery, and a positive electrode and a battery equipped with it having oxidation resistance, electrolytic solution resistance, and large porosity, suiting industrial production, and not causing a problem of short circuit even if it is wound with an electrode group. <P>SOLUTION: The collector of a positive electrode for lithium based secondary battery is formed as a three-dimensional porous body comprising nonwoven fabric made of resin, a conductive layer formed on a surface of the nonwoven fabric, and an aluminum electrolytic plating layer formed on a surface of the conductive layer by using a bath including aluminum salt in a nonaqueous solvent. <P>COPYRIGHT: (C)2010,JPO&INPIT |
