Negative electrode for secondary battery, secondary battery, battery pack, electric vehicle, power storage system, power tool and electronic equipment |
| abstract |
A secondary battery capable of obtaining excellent battery characteristics is provided. A secondary battery includes a positive electrode, a negative electrode, and an electrolytic solution, and the negative electrode includes a plurality of first negative electrode active material particles, a plurality of second negative electrode active material particles, and a negative electrode binder. The first negative electrode active material particles include a material containing carbon as a constituent element, and the second negative electrode active material particles include a material containing silicon as a constituent element. The negative electrode binder contains polyvinylidene fluoride, and a part of the negative electrode binder exists so as to cover a part of the surface of the second negative electrode active material particles. The ratio M2 / M1 of the amount M2 of the negative electrode binder present on the surface of the second negative electrode active material particle and in the vicinity thereof to the amount M1 of the negative electrode binder present on the surface of the first negative electrode active material particle and in the vicinity thereof Is greater than one.
