Abstract:
The present invention aims to provide an electrode mixture which shows little change in viscosity even after 24 hours from the preparation of the mixture and enables production of an electrode having a high electrode density and excellent flexibility and is capable of giving excellent electric properties to the resulting cell. The present invention relates to an electrode mixture including a powdery electrode material; a binder; and an organic solvent, the binder including polyvinylidene fluoride and a fluorine-containing polymer including a polymer unit based on vinylidene fluoride and a polymer unit based on tetrafluoroethylene, the fluorine-containing polymer including the polymer unit based on vinylidene fluoride in an amount of 80.0 to 90.0 mol % based on all the polymer units, the polyvinylidene fluoride having a number average molecular weight of 150,000 to 1,400,000.
