Abstract
A manufacturing method for a current collector includes dispersing and agitating a fluorine-based resin and conductive particles for 5 to 60 minutes at 1000 to 5000 rpm, dispersing and agitating the fluorine-based resin and conductive particles for 10 to 120 minutes at 2000 to 7000 rpm. The resin layer includes a fluorine-based resin and conductive particles, has a thickness of 0.3 to 20 μm. The current collector has one or more of: (1) average diameter of the particles is 0.5 to 25 μm, and a surface occupying ratio of the particles at a surface is 10 to 50%; (2) surface resistance of the resin layer at 20° C. is 1.0 to 10Ω, resistance after heating at 220° C. is 200 to 600Ω, and (3) surface resistance of the resin layer at 20° C. is 1.8 to 9.7Ω, resistance after heating at 180° C. is 209 to 532Ω.
