摘要:
Hollow core-shell structured porous Si-C nanocomposites with void space up to tens of nanometres are designed to accommodate the volume expansion during lithiation for high-performance Li-ion battery anodes. An initial capacity of similar to 760 mA h g(-1) after formation cycles (based on the entire electrode weight) with similar to 86% capacity retention over 100 cycles is achieved at a current density of 1 A g(-1). Good rate performance is also demonstrated.
