What is graphite? Graphite is a naturally occurring form of carbon characterized by its layered structure, which gives it ...

The majority of naturally appearing graphite has hexagonal stacking, making it one of the most “ordinary” materials on Earth. The structure of graphite crystal is a repetitive pattern. This pattern ...

As global demand for electric vehicles and renewable energy storage surges, so does the need for affordable and sustainable battery technologies. A ...

RIGHT: The structure of graphite with atoms of carbon arranged in layers. Carbon fibres are long, thin strands of carbon. They are strong, stiff and light. Bundles of carbon fibres are woven ...

However, the same graphite structure fails when it comes to sodium or potassium. Their atoms are simply too big and interactions too complex to slide in and out of graphite’s tightly packed layers.
