In the past, we have modified PAN fibers with potassium permanganate, shortened the oxidation time[ 14], enhanced the tensile strength of the carbon fibers[5], and studied the changes in the physical properties and microstructure of fibers during the process of oxidation[6]. in this article, the study is focused on the changes in the microstructure of PAN graphite fibers during the graphitizati...

Resource- and energy-efficient biomass exploitation for green graphite production is one of the most effective strategies satisfying demand while minimizing energy consumption carbon emissions. This study investigated from waste its applications to establish a industry. Biomass pyrolysis catalytic graphitization biochar were studied first produce graphite. The optimized exhibited reversible cap...

Enhancements of oxygen-containing groups on the surface activated carbons (ACs) and degree graphitization in their structures allow a potential solution for development cathode materials Lithium Sulfur Batteries (LSBs). Despite two factors having been researched considerably, most applicable electrochemical performances method have not reached. Here chemical properties commercial AC terms funct...

The paper presents the characteristics of products annealing at temperatures 2400 and 3000 °C unburned carbon from coal fly ash in terms its possible use as a starting material graphitization process. An amorphous substance (organic substance) with an admixture some minerals has been found samples subjected to graphitization. However, graphite phase is dominant Studies have also shown diverse g...

We have characterized both the direct current conductivity and morphology of a wide range of films made from bundled nanotubes, produced by a selection of commercial suppliers. The conductivity increases with increasing nanotube graphitization but decreases with increasing film porosity P and mean bundle diameter D . Computational studies show that the network conductivity is expected to scale ...

The development of lithium-ion batteries (LIBs) has become an important aspect advanced technologies. Although LIBS have already outperformed other secondary batteries, they still require improvement in various aspects. Most crucially, graphite, the commercial anode, a lower capacity than emerging materials. goal this research is to develop carbon-based materials from sustainable sources. Banan...
