For graphite pellets, just add elbow grease

A new report shows how chemically altered graphene powder can be pressed into a lightweight, semiporous solid that retains many of the strong and conductive qualities of graphite, the form of carbon found in pencils, lubricants and many other products that normally requires high-temperature processing to make. Researchers demonstrated that the environmentally friendly, scalable process can be done in minutes by hand by grinding chemically modified graphene into a powder and using a hand-powered press to squeeze the powder into a solid pellet. The researchers believe that the combination of light weight, high strength and high conductivity is appealing for applications such as conducting cables and electrodes.
