Title:
POLYMER COMPOSITION FOR NONAQUEOUS SECONDARY BATTERIES AND NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2021102710
Kind Code:
A
Abstract:
To provide a polymer composition for nonaqueous secondary batteries that can express excellent cycle characteristics and initial capacity, and a nonaqueous secondary battery.SOLUTION: A polymer composition for nonaqueous secondary batteries contains polymer particles. The polymer particles have a Young's modulus of 1.5 GPa or less, an elastic deformation power of 50% or less, and an electrolyte swelling rate of 1.5 or less. Preferably, the polymer particles respectively have a core-shell structure comprising a core part and a shell part, the core part having a Young's modulus of 0.1 GPa or less in the polymer composition for nonaqueous secondary batteries.SELECTED DRAWING: None
