"Graphite has seen a host of swings over the last number of years. Graphite has not experienced the price spikes other battery metals have gone through.Prices for large flake graphite have recovered from their lows of US$750 tonne in 2016 to approximately $1,200 tonne as of February 2019, prices are still well below the 2012 peak of US$2,800 tonne. Prices jumped in second half of 2017 --  as much as 40% thanks to an improving steel industry, production problems in China and continued demand from the lithium ion battery industry. But since that point, prices have been relatively flat. That said, batteries are now approximately 25% of the market -- and are growing rapidly. 
"Graphite prices really are a function of flake size and purity. In short, the bigger the better: large (+80 mesh) and extra-large flake (+50 mesh) and 95% and more carbon varieties bring premium pricing to the table."
