Where is all the graphite going to come from?

The projected number of electric cars sold per year in 2020 is about six million. That is 1.59 million tonnes of graphite. Where is all this graphite going to come from? The differential, or the amount of graphite demand increase each year indicates that one, or more, 100,000 tonne per year mines could open each year solely dedicated to electric cars and this market would not be filled.
