ORNL researchers created and tested two methods for transforming coal into the scarce mineral graphite, which is used in batteries for electric vehicles and renewable energy storage.

By exposing this simplified coal to pressure and high temperature—about 3,000 Kelvin, or nearly 5,000 Fahrenheit—they could take a first step in studying its conversion to graphite.

The ash that's left is not rich enough in carbon to produce graphite, Lara-Curzio said. Coal refuse from mines and processing plants is typically made of fine particles too small to burn or low ...

ORNL’s electrochemical process creates graphite from coal byproducts at 1,500 degrees Fahrenheit. This contrasts with the conventional method, which requires temperatures over 4,000 degrees ...

The shift could also allow us to charge them using carbon-neutral energy sources. The kicker is that each Tesla model S’s lithium-ion batteries require some 100 pounds of graphite. And scientists have ...

Coal India has bagged its first non-coal mineral asset, marking its entry into the graphite mining sector. What Happened: The firm informed of its foray into non-coal mineral mining in a press ...

Mining companies are ramping up supplies of critical minerals for rechargeable batteries such as lithium, cobalt and nickel. Graphite, a key battery component, has largely been overlooked. That is ...
