Embedding silicon nanoparticles in graphene based 3D framework by cross-linking reaction for high performance lithium ion batteries

A Si/reduced graphene oxide composite with 3D framework is constructed by a typical cross-linking reaction between polyacrylamide and graphene oxides, which delivers a high reversible capacity of 1610 mA h g−1 at 1.2 A g−1 after 200 cycles, good rate capability, and cycling stability with negligible capacity degradation over 200 cycles.
