Product performance and application:

Graphene is one of the most interesting new materials. Its structure is composed of two symmetrical and nested sublattices. The doping of heterogeneous atoms is an important method to break the symmetry structure and modulate its physical properties.

Nitrogen atoms have similar sizes to carbon atoms and are relatively easy to be doped into the lattice of graphene. Therefore, nitrogen doping plays an important role in the research of graphene materials. In monolayer graphene, substitution doping can be used to alter its electronic properties during growth.

Nitrogen doping of graphene can open the band gap and adjust the type of conduction, change the electronic structure, and improve the density of free carriers, so as to improve the conductivity and stability of graphene. In addition, the introduction of nitrogen-containing atomic structure into the carbon grid of graphene can increase the active sites adsorbed on the surface of graphene, thus enhancing the interaction between metal particles and graphene. Therefore, the application of nitrogen-doped graphene to energy storage devices has more superior electrochemical properties and is expected to develop into a high-performance electrode material. Existing studies have also shown that nitrogen-doped graphene can significantly improve the capacity characteristics, rapid charge and discharge capacity and cycle life of energy storage materials, and it has great application potential in the field of energy storage.

Nitrogen-doped graphene is one of the important ways to functionalize graphene and plays a key role in expanding the application field of graphene. Nitrogen-doped graphene can significantly improve the capacity characteristics, rapid charge and discharge capacity and cycle life of energy storage materials, and has great application potential in chemical energy storage systems such as supercapacitors, lithium ion batteries, lithium sulfur batteries and lithium empty batteries.
