Electrochemical characteristics of Si/Mo multilayer anode for Li ion batteries

We have prepared the Si/Mo multilayer by alternate deposition with a multi-gun rf/dc magnetron sputtering system. A current collector was Cu foil that had a rough surface. Pre-treatment with plasma on the surface was performed in order to improve adhesion between an electrode and substrate and to remove contamination on the surface. The structural and electrochemical characteristics of yhe Si/Mo multilayer were investigated. The initial capacity of the Si thin film rapidly degraded after 40 cycles, whereas the multilayer maintained more than 90 % of the initial capacity (2653 mAhg-1) after 100 cycles.
