Owing to its high theoretical specific capacity (4200 mAh·g-1), silicon is a promising candidate to replace graphite as the anode in lithium ion batteries (LIBs). However, low intrinsic electric conductivity and dramatic volume change (~ 300%) during the process of lithiation and delithiation result in electrode pulverization and capacity loss with cycling, accordingly, the application of silicon as an anode in LIBs has been severely hindered. We will discuss the structure of silicon electrode including synthesis of Si-based composites,the selection of binder for silicon and the fabrication of binder-free Si-based electrode, as well as the electrolyte additive to improve the cycle performance of the battery.
