Abstract:
This review provides a summary of the progress in research on various Si-based thin films as anode
materials for lithium-ion batteries. The lithiation mechanism models, different types of materials from
pure monolithic Si thin film to Si-based three-dimensional structured composite thin films, the effect of
liquid and solid-state electrolytes on the performance of Si were considered and various available
preparation techniques were discussed. A table summarizing important information on such systems
including the thin film features, preparation methods and conditions, electrochemical test conditions
and obtained results in order to elucidate the approaches used to prepare a stable thin film anode with
high capacity and long cycle life is provided. We believe that this review will help the researchers to find
some answers and induce some new ideas.
