METHOD FOR MANUFACTURING NEGATIVE ELECTRODE SLURRY FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NEGATIVE ELECTRODE SLURRY FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

WIPO Patent Application WO/2018/211610

A1

The present invention addresses the problem of providing a method for manufacturing a negative electrode slurry for a non-aqueous electrolyte secondary battery and a negative electrode slurry for a non-aqueous electrolyte secondary battery which make it possible to suppress expansion and contraction of a silicon-based material while reducing a binder component that does not contribute to battery performance, improve electrode performance, and reduce manufacturing cost. A method for manufacturing a negative electrode slurry for a non-aqueous electrolyte secondary battery including a silicon-based material comprises performing, with respect to a negative electrode material of a non-aqueous electrolyte secondary battery which includes a silicon-based material and contains 4 to 12 wt% by solid content ratio of a thermosetting resin as a binder component, dispersion and mixing using a dispersion/mixing device to cause cavitation.
