摘要： The invention provides a binder for a secondary battery leading to an excellently high density of an electrode, excellent adhesiveness to a current collector, excellent flexibility of an electrode, and excellent viscosity retention of slurry. The binder for a secondary battery contains a fluorine-containing polymer (A) and polyvinylidene fluoride (B). The fluorine-containing polymer (A) contains a polymerized unit based on vinylidene fluoride, a polymerized unit based on tetrafluoroethylene, and a polymerized unit based on a monomer (2-2) represented by the following formula (2-2):
wherein R 5 , R 6 , and R 7 are each independently a hydrogen atom or a C1-C8 hydrocarbon group; R 8 is a C1-C8 hydrocarbon group; and Y 1 is an inorganic cation or an organic cation.-

摘要： The invention provides a fluororesin that is less likely to suffer blistering or cracking even when rapidly decompressed from a high-temperature and high-pressure state. The fluororesin contains a vinylidene fluoride unit. The vinylidene fluoride unit represents 10.0 to 100 mol% of all the monomer units constituting the fluororesin. The fluororesin exhibits a weight loss of 0.1% or less after heated at 300°C for two hours.
