NEGATIVE ELECTRODE FOR LITHIUM-ION BATTERY, PRODUCTION METHOD THEREFOR, AND LITHIUM-ION BATTERY |
摘要 |
A negative electrode for a lithium ion battery 10 includes a negative electrode current collector 11, a negative electrode active material layer 14, and a lithium silicate layer 15. The negative electrode active material layer 14 contains silicon. The lithium silicate layer 15 contains lithium, oxygen, and silicon forming a Li-O-Si bond, and is formed at the interface between the negative electrode current collector 11 and the negative electrode active material layer 14. The negative electrode active material layer 14 and the lithium silicate layer 15 may be composed of columnar bodies. |
