As the world depends more on electric devices and clean energy, the demand for battery materials like lithium, cobalt and nickel is rising quickly. These materials are limited and often come from only ...

Rice University researchers have developed a two-step recycling method that pairs microwave-induced plasma with citric acid ...

Microwave plasma method recovers 95% of battery metals and regenerates graphite using mild, low-impact solvents.

Critical minerals such as those used in lithium-ion batteries come in limited supply and are concentrated in specific regions around the world. Securing a reliable supply of these materials is a ...

A lab in the United States has made high-quality graphite from coal waste. Researchers at the NETL unlocked a low-temperature synthesis process to turn coal into critical mineral graphite with a lower ...
