Abstract

Provided is a method for manufacturing a current collector provided with a conductive layer that can keep a high resistance only at a high temperature. The method includes dispersing a carbon material in an organic solvent to prepare a carbon material dispersion solution, dispersing polyvinylidene fluoride in an organic solvent to prepare a resin dispersion solution, mixing the carbon material dispersion solution, the resin dispersion solution, and water, to prepare a composition for conductive layer formation, and forming a conductive layer on a surface of a current collector by applying the composition for conductive layer formation and thereafter drying the composition.
