▎ 摘 要
A three-dimensional polymeric carbon nitride/graphene framework (CN/GF) was fabricated by the ionic self-assembly of graphene oxide and protonated polymeric carbon nitride nanosheets. As the cathode material in lithium-ion batteries, CN/GF showed an excellent reversible capacity of 184mAhg(-1) at 0.05Ag(-1) for 150cycles and maintained the capacity of 60mAhg(-1) at 5Ag(-1).
