Silicon-Carbon composite anodes for lithium rechargeable batteries (SiC)

Silicon anodes, being high theoretical capacity active materials, exhibit immense potential to replace the carbon-based anodes (360mAh/g) that have reached their capacity limit with the recent emergence of electric vehicles. However, despite their high capacity (3,750mAh/g), conventional silicon anodes have been hindered by issues such as large volume expansion and low conductivity upon charging/discharging, making them difficult to use for prolonged periods. In contrast, SKC's silicon anodes have a composite structure in which silicon nanoparticles are uniformly distributed into an oxygen layer and a carbon layer. This unique composition suppresses the cycle degradation caused by volume expansion and improves electric conductivity. Consequently, SKC's silicon anodes provide a superior alternative as rechargeable battery anode active materials, characterized by maximal high capacity, extended cycle life, and superior rate capability performance.​
