Abstract
Silicon hollow carbon nanofiber (HCNF) anode materials can be considered as a promising alternative for the conventional graphite electrode due to its 10 times higher theoretical capacity (4200 mAh g-1 vs 372 mAh g-1). However, it suffers from the fast capacity loss and limited cycle life because of volume expansion of Si at the lithiation process, therefore a considerable amount of Li ions is irreversibly trapped in the Si active sides. Generally, HCNF with its unique structure could withstand large volume change of Si.
