摘要

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.
