Anode active material, lithium secondary battery employing the same, and method of preparing the anode active material |
| 摘要 |
An anode active material, a lithium battery including the anode active material, and a method of preparing the anode active material are provided. The anode active material includes an alloy containing silicon (Si), titanium (Ti) and nickel (Ni) elements, wherein the alloy includes a Si phase and an alloy phase, and a peak intensity ratio (I(111)/I(220)) of Si(111) to Si(220) plane in a X-ray diffraction spectrum of the Si phase is from about 1.0 to about 1.5. |
