Hollow core–shell structured porous Si–C nanocomposites for Li-ion battery anodes

Author affiliations

Abstract

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 ∼760 mA h g−1 after formation cycles (based on the entire electrode weight) with ∼86% capacity retention over 100 cycles is achieved at a current density of 1 A g−1. Good rate performance is also demonstrated.
