A splash of graphene can improve battery materials.Byline: ANI Washington, September 23 (ANI): In a new research, scientists have determined that a splash of graphene can improve battery materials. Researchers would like to develop lithium-ion batteries using titanium dioxide, an inexpensive material. But titanium dioxide on its own doesn't perform well enough to replace the expensive, rare-earth metals rare-earth metals, in chemistry, group of metals including those of the lanthanide series and actinide series, usually yttrium, sometimes scandium and thorium, and rarely zirconium. or fire-prone carbon-based materials used in today's lithium-ion batteries. To test whether graphene, a good conductor on its own, can help, PNNL's (Pacific Northwest National Laboratory The Pacific Northwest National Laboratory (PNNL) is one of nine United States Department of Energy (DOE) multiprogram national laboratories. The laboratory PNNL is located in Richland, Washington, and operates a marine research facility in Sequim, Washington. ) Gary Yang and colleagues added graphene, sheets made up of single carbon atoms, to titanium dioxide. When they compared how well the new combination of electrode electrode, terminal through which electric current passes between metallic and nonmetallic parts of an electric circuit. In most familiar circuits current is carried by metallic conductors, but in some circuits the current passes for some distance through a materials charged and discharged electric current, the electrodes Electrodes Tiny wires in adhesive pads that are applied to the body for ECG measurement. Mentioned in: Electrocardiography containing graphene outperformed the standard titanium dioxide by up to three times. Graphene also performed better as an additive than carbon nanotubes.
