Abstract
An insulation paste for a current collector for a lithium-ion secondary battery contains an inorganic filler (A), a binder (B), a dispersion resin (C), and a solvent (D), wherein the insulation paste has a viscosity (shear rate of 1 s−1) of 2000 mPa·s or more, and has a TI value of greater than 1, and the TI value is a ratio of the viscosity at a shear rate of 1 s−1 to the viscosity at a shear rate of 1000 s−1.
