Title: Hollow Core-Shell Structured Porous Si-C Nanocomposites for Li-Ion Battery Anodes

Abstract

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