Title:
METHOD FOR MANUFACTURING BINDER COMPOSITION FOR ALL-SOLID-STATE SECONDARY CELL, METHOD FOR MANUFACTURING SLURRY COMPOSITION FOR ALL-SOLID-STATE SECONDARY CELL, METHOD FOR MANUFACTURING SOLID-ELECTROLYTE-CONTAINING LAYER, AND METHOD FOR MANUFACTURING ALL-SOLID-STATE SECONDARY CELL
Document Type and Number:
WIPO Patent Application WO/2022/044815
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for manufacturing a binder composition for an all-solid-state secondary cell with which it is possible to form a solid-electrolyte-containing layer that can manifest exceptional output characteristics and cycle characteristics in an all-solid-state secondary cell. This method for manufacturing a binder composition for an all-solid-state secondary cell involves manufacturing a binder composition for an all-solid-state secondary cell containing a polymer and an organic solvent, the method for manufacturing a binder composition for an all-solid-state secondary cell being characterized by including a moisture removal step for using a dehydrating agent containing a group 13 element and/or a group 14 element to obtain a composition (X) that contains the polymer and the organic solvent and that has a water content of 200 ppm or less, and a transition metal removal step for removing transition metals contained in the composition (X) by magnetism and obtaining a binder composition for an all-solid-state secondary cell.
