<P>PROBLEM TO BE SOLVED: To provide a sheet for a positive pole of lithium ion secondary battery, which is obtained by layering a positive pole active material layer on a sheet for the positive pole, capable of significantly lowering the resistance of an aluminum foil surface and significantly suppressing missing of carbon nanofiber from the aluminum foil surface. <P>SOLUTION: The sheet for positive pole of lithium ion secondary battery has an aluminum foil surface coated with carbon nanofiber. The carbon nanofiber has an average fiber diameter of 5-80 nm, an average fiber length of 50-5,000 nm and an average specific surface area of 100-1,000 m<SP POS="POST">2</SP>/g. <P>COPYRIGHT: (C)2013,JPO&INPIT |
