The invention relates to silicon-containing compositions, methods of preparing these compositions and methods of depositing amorphous silicon originating from these compositions onto substrates to form composites for use, for example, as anodes in lithium ion batteries. An amorphous silicon-containing coating, such as a thin film, is formed on the substrate. The coating can further include carbon and crystalline silicon.
