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...

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...

by Debra Fiakas, CFA Greater energy density or the amount of energy stored is the mission of every battery developer.  The higher the energy density, the longer a battery can serve its owner.  Scientists have been adjusting circulating chemistry, cloaking electrodes in exotic metals, and otherwise tinkering with conventional battery designs.  Debate even spills over into the raw material supply chain as it has recently over the use of expensive and sometimes difficult to source cobalt as an additive to lithium ion battery designs.   Others are trying to tame silicon for use in battery anodes. Perhaps the most daring developers have abandoned conventional battery design...
