BINDER RESIN FOR NONAQUEOUS SECONDARY BATTERY ELECTRODE, BINDER RESIN COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY ELECTRODE, SLURRY COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY ELECTRODE, ELECTRODE FOR NONAQUEOUS SECONDARY BATTERY, AND NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2013/081152
Kind Code:
A1
Abstract:
A binder resin for a nonaqueous secondary battery electrode, said binder resin satisfying the requirement IS≥30 (wherein IS stands for the sum of scattering intensities measured within a particle diameter range of 1-100 nm) when dissolved in water to give a solution having a concentration of 5 mass% and then subjected to particle size distribution measurement by the dynamic light scattering method at 25oC. The binder resin for a nonaqueous secondary battery electrode according to the present invention comprises a polymer (B) that has a structural unit represented by general formula (11) and a specific structural unit. The binder resin for a nonaqueous secondary battery electrode according to the present invention comprises a polymer (α) that has a specific structural unit and a structural unit represented by general formula (22), and/or a mixture of a polymer (β1) that has a specific structural unit with a polymer (β2) that has a structural unit represented by general formula (22).
