NEGATIVE ELECTRODE ACTIVE MATERIAL FOR ENERGY STORAGE DEVICES AND METHOD FOR MAKING THE SAME |
| 摘要 |
The described embodiments provide an energy storage device that includes a positive electrode including an active material that can store and release ions, a negative electrode including an active material that is a lithiated nano-architectured active material including tin and at least one stress-buffer component, and a non-aqueous electrolyte including lithium. The negative electrode active material is nano-architectured before lithiation. |
