Graphit nanopulver
WebTo improve the electrical conductivity of negative electrodes of lithium ion batteries, we applied a direct CVD synthesis of carbon nanomaterials on the surface of graphite particles. To prepare a catalyst, two alternative approaches were utilized: colloidal nanoparticles (NPs) and metal (Ni and Co) nitrate salt precursors deposited on the graphite surface. Both … WebGraphite is a natural crystalline form of the element carbon (chemical symbol C). Graphite is carbon in its crystalline form. It is an excellent conductor of both electricity and heat. Graphite is very stable and chemically inert. It is also very soft and has a high lubricity.
