| Research Abstract |
Thick-film electrodes of composite active materials consisted of Si and various metal silicides were prepared by mechanical alloying followed by gas deposition for anodes of Li-ion batteries. We investigated a relationship between the performance of these electrodes and properties of the silicides, the electrical resistivity, the referential breaking strength, and the thermodynamic stability. The LaSi_2/Si composite electrode exhibited superb cycling performance. It is suggested that thermodynamically stable LaSi_2 in the composite electrode can improve the electrical conductivity of the electrode and can release the stress induced by a volumetric change of Si for a long period.
