"To satisfy the steel market alone, annual graphite demand is expected to rise 8% CAGR to 2020 from 1.1 million tonnes to 1.5 million tonnes. Batteries and high-tech application needs are projected to be dramatic enough to require a 600% increase in annual flake graphite production. Only flake graphite can be used in the over 200-known applications that require graphite as an additive and is the only natural form of graphite that can be used to make the spherical graphite used in lithium-ion batteries. Thus, purified, spherical graphite currently sells for between $4-6,000/tonne, more than twice the price of high quality flake graphite. Furthermore, the British Geological Survey listed graphite, along with antimony and rare-earths, as most at risk of a global supply disruption."". ---dec9/16, Investorintel
