NEGATIVE ELECTRODE MATERIAL FOR LITHIUM ION SECONDARY BATTERIES, AND METHOD FOR EVALUATING SAME |
| 摘要 |
There is provided a negative electrode material for lithium ion secondary batteries having a structure in which in charged and discharged states, a LixSi compound (2) exists in the inside of a Li oxide (1) and the LixSi compound is dispersed in the inside of the Li oxide. The negative electrode material, in which volume change resulting from charge/discharge is suppressed, has excellent performance as a negative electrode material for lithium ion secondary batteries. |
