摘要： A binder solution for providing an electrode suitable for use in non-aqueous-type electrochemical devices, such as a battery and an electric double layer capacitor, is formed by dissolving a vinylidene fluoride polymer having an inherent viscosity (and thus a polymerization degree) higher than a conventional level in an organic solvent. An electrode-forming composition is formed by dispersing powdery electrode material in the binder solution and is applied onto an electroconductive substrate while avoiding the gelation of the polymer, followed by drying, to form a composite electrode layer, which retains the powdery electrode material at a smaller amount of vinylidene fluoride polymer than a conventional level and is well resistant to a non-aqueous electrolytic solution.

摘要： A vinylidene fluoride polymer binder solution for forming an electrode for a non-aqueous-type battery is formed by adding an acid, preferably an organic acid, as a stabilizer to a solution of a vinylidene fluoride polymer in an organic solvent. The acid is preferably added in an amount sufficient to ensure a pH of at most 9 when measured with respect to a 10-times dilution of the binder solution with deionized water. The acid addition is effective for preventing a problematic viscosity increase in the binder solution and also gelling of an electrode-forming composition formed by adding a powdery electrode material in the binder solution.
