New technology of German open porous graphite electrode new lithium ion channel

German researchers first introducing nickel nanoparticles surface of graphite materials, then rapid heating in an atmosphere of hydrogen, the surface of the metal nickel nanoparticles will play a catalytic role, to the carbon atoms from the graphite crystal lattice, combine with hydrogen atoms into methane gas. In this process, the metal nickel nanoparticles under the effect of capillary effect, will be "inhalation" tiny "cavity" in graphite material surface, and continue to catalytic chemical reaction and gradually in-depth internal graphite material. The nano "tunnel" structure has wide application prospect, such as through the process of preparation of porous graphite materials as electrode materials of lithium ion battery, charging can greatly shorten the time required for; In medical field, the porous graphite material is used as a directional release drug carrier can be a long time. And if use the technology of crystal structure of graphite with similar but not with conductive properties of the material (such as boron nitride) carry on the processing, the formation of the "tunnel" structure can be used as the scaffold material of nano electronic components, such as new type of sensors and solar cells.
