This work addresses the fabrication of an integrated structured Si/CNT/G composite anode by simple, low-temperature heat treatment and is used as a Li-metal-free anode for advanced Li-S batteries. The tough framework of CNTs/G endow required structural stability and intrinsic conductivity to Si nanoparticles and help to mitigate the volume changes and other drawbacks of Si. The fabricated Si-sulfur full-cell delivered high energy densities which are suitable for Li+ energy storage applications and a worthy substitute to replace unsafe Li-metal anodes.
