Graphene is a one-atom thick sheet of carbon atom arranged in a honeycomb lattice.  It is an exceptional conductor of heat and electricity and its strength is unparalleled.  Although synthetic graphite can be used to produce graphene and it offers the benefit of consistency, natural graphite is far less expensive as a source material.  Synthetic graphite is made by combining petroleum coke with carbon black in a high heat process that burns up profits as it purifies the carbon. There are several methods for producing graphene.  Exfoliation of natural graphite is perhaps the most common alternative because it produces the least defects and leaves...

Fuel cell stocks are publicly traded companies whose business involves fuel cells, devices for efficiently converting the energy in a fuel (often hydrogen) directly into electricity by chemical means, without combustion.

The post “Integrated Graphene Producers” featured several graphene producers with novel business models that marry captive graphite sources to the technology and knowhow to produce graphene.  These are not the only graphite producers.  Although not as elegant as graphene with its svelte single-atom profile, the market for graphite has its appeal as well. Graphite has been a staple in steel industry crucibles, foundry molds and automobile brake linings.  These days graphite has moved into another even more important place in cars  -  lithium ion batteries that make electric vehicles viable as replacements for gas guzzling cars and trucks. Spherical graphite is especially desirable because the graphite anodes hold...

Build up of the graphene materials industry has progressed a bit more slowly than originally expected a decade ago as scientists and engineers peered through their electron microscopes at single atoms of carbon and counted their many attributes.  At the time the potential to improve performance in end products like metal alloys and electronics seemed limitless.   Unfortunately, reality has not imitated early dreams.  Those companies that have brought graphene to the commercial market will attest to the challenges of jumping off the laboratory bench and into a factory. Even more frustrating is the sourcing of graphene to use in research, product development and...
