Abstract: Silicon (Si) holds great promise for lithium ion battery anode. The significant challenges on Si anodes are the adverse effect of large volume changes upon lithiation and delithiation. This review describes the attractive advantages of the binders in solving the volume effect of Si anodes, and discusses the recent development and multi-functional trends of Si-based binders, eventually summarizes the research progress of the binders in improving the electrochemical performances of Si anodes. Finally, we look forward to new ideas and new directions for the development of binders for Si anode in the future.
