Researchers at Beihang University in Beijing have developed a new Li-sulfur battery using honeycomb-like sulfur copolymer uniformly distributed onto 3D graphene (3D cpS-G) networks for a cathode material and a 3D lithiated Si-G network as anode. In a paper published in the RSC journal Energy & Environmental Science , they reported that the full cell exhibits superior electrochemical performances in term of a high reversible capacity of 620 mAh g -1 , ultrahigh energy density of 1147 Wh kg −1 (ba
