Electrode mixture slurry for lithium secondary batteries, and electrode and lithium secondary battery that use said slurry

Disclosed is an electrode mixture slurry that is stable with no gelation, and additionally disclosed are an electrode with good adhesion between the binder and collector and with ample flexibility, and a lithium secondary battery with excellent battery characteristics. The electrode mixture slurry for lithium secondary batteries comprises an electrode active material, a binder, and an organic solvent. The binder is a fluorine-containing polymer represented by the composition formula: (VDF) m (TFE) n (HFP) l (In the formula, VDF represents structural unit derived from vinylidene fluoride; TFE represents a structural unit derived from tetrafluoroethylene; HFP represents a structural unit derived from hexafluoropropylene; 0.45 ≦ m ≦ 1; 0.05 ≦ n ≦ 0.5; 0 ≦ 1 ≦ 0.1; where m + n + l = 1.), and includes a solvent-soluble thermoplastic resin that is not a fluorine-containing polymer.
