• Amorphous lithium-silicon compounds are promising materials in order to improve pure silicon as a high-capacity anode material in lithium-ion batteries. We demonstrated that it is possible to produce amorphous Li x Si ( x 0.4) thin films by reactive ion-beam co-sputtering of a segmented solid state target composed of metallic lithium and elemental silicon. At the surface a graded Li x SiO y layer of some nanometer thickness is formed by contact with air which seems to prevent decomposition of the Li x Si. Amorphous Li x Si ( x = 0.4) thin films were produced by reactive ion-beam co-sputtering for use as anode materials in Li-ion batteries.
