| titleOfInvention | Negative electrode for lithium-ion secondary battery |
| abstract | PROBLEM TO BE SOLVED: To provide a technique capable of preventing uneven distribution of a non-aqueous electrolyte solution in a negative electrode active material layer and improving high rate deterioration resistance. A negative electrode active material layer of a negative electrode 10 for a lithium ion secondary battery disclosed herein includes a negative electrode active material 16 and polymethylmethacrylate (PMMA) 18. In the negative electrode 10 disclosed herein, the PMMA 18 having a monolith structure exists between the particles of the negative electrode active material 16. Since the PMMA 18 having a monolith structure has high strength, it can restrict the expansion of the negative electrode active material 16 and prevent the nonaqueous electrolytic solution from flowing out from the negative electrode active material layer 14. In addition, since the PMMA having a monolith structure has a plurality of pores formed therein, the non-aqueous electrolyte can be retained therein. Therefore, according to the negative electrode 10 disclosed herein, it is possible to prevent uneven distribution of the non-aqueous electrolytic solution from occurring in the negative electrode active material layer 14 and improve high rate deterioration resistance.
