Title:
ADHESIVE COMPOSITION, SEPARATOR STRUCTURE, ELECTRODE STRUCTURE, NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/230219
Kind Code:
A1
Abstract:
An adhesive resin composition that contains an adhesive resin, provided on the surface of a separator or an electrode of a non-aqueous electrolyte secondary battery, wherein the adhesive resin contains at least one vinylidene fluoride copolymer (a) that contains a structural unit derived from vinylidene fluoride and a structural unit derived from a monomer that is copolymerizable with vinylidene fluoride. The turbidity of an NMP solution of the adhesive resin is 2 to 95 (inclusive), the solution viscosity (A) of an acetone solution of the adhesive resin is 350 to 20000 mPa•s, and the ratio (A)/(B) of the solution viscosity (A) to the solution viscosity (B) of the NMP solution of the adhesive resin is 1 to 15 (inclusive).
