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 184 mA h g −1 at 0.05 A g −1 for 150 cycles and maintained the capacity of 60 mA h g −1 at 5 A g −1 .
