| 摘要 |
The present invention relates to a binder for a nonaqueous electrolyte secondary cell, a binder solution for the nonaqueous electrolyte secondary cell, and an anode mixture for the nonaqueous electrolyte secondary cell having excellent adhesiveness, allowing reduction of initial irreversible capacity of the nonaqueous electrolyte secondary cell when manufacturing the cell, having an excellent capacity retention rate during fast discharge, and allowing improvement of charge cycle characteristics, this binder for a nonaqueous electrolyte secondary cell including at least a functional-group-containing vinylidene fluoride polymer and a polyvinyl alcohol having saponification of 35-90 mol percent, the polyvinyl alcohol being 5-93 mass percent per the total 100 mass percent of the functional-group-containing vinylidene fluoride polymer and the polyvinyl alcohol. |
