Some thoughts
The 200 mile range Li-ion batteries in the Tesla contains roughly 100Kg of graphite for the electrodes in its batteries.
I often wonder what the average driving range would be for all makes of electric vehicles would be if they used Vanadium, Lithium, Phosphate Batteries?
Its estimated that if electric cars obtained a 5% market penetration, it could create a market of roughly 800,000 tonnes per year for battery grade graphite alone, which along with vanadium could make Energizer Resources a major supplier for both minerals..
Presently the natural graphite market provides a total of 1,000,000 tonnes per year of natural graphite for all uses.
