Covalent organic polymer (COPs) is a kind of crystalline microporous polymer, which has been widely used due to its many excellent properties, such as high specific surface area, abundant pore size structure, low weight density. Here, melamine-based COPs with the lamellar structure were synthesized using melamine and 1,4-dibromobutane. The thickness of the flake is about 3.5 nm. COPs/rGO composites were prepared by in situ doping graphene (rGO) and the electrochemical performance as a lithium-ion battery anode materials was studied. The composite materials show a reversible capacity of 420 mAh/g after 100 cycles at a current density of 50 mA/g, at the same time, it shows excellent high current density and rate capability.
