Negative electrode for nonaqueous electrolyte secondary batteries, and nonaqueous electrolyte secondary battery using same |
| abstract |
Provided is a technique capable of further improving the cycle characteristics in a negative electrode for a non-aqueous electrolyte secondary battery in which a silicon-based negative electrode active material and a carbon-based negative electrode active material are used in combination as a negative electrode active material, and constituent components of the electrode are not bound to each other via a binder. The negative electrode for a non-aqueous electrolyte secondary battery according to the present invention has a configuration in which a negative electrode active material layer containing a negative electrode active material is formed on a surface of a current collector. The negative electrode active material contains composite secondary particles in which silicon-based negative electrode active material particles and carbon-based negative electrode active material particles are bound to each other via a binder. Here, the content of the binder in the composite secondary particles is 1% by mass or more with respect to the total mass of the silicon-based negative electrode active material particles and the carbon-based negative electrode active material particles. Further, in the negative electrode active material layer, the composite secondary particles are characterized to exist in a state of being not bound to each other via a binder. |
